The Creativity in the Design of Hospital Inpatient Rooms with Biophilic Criteria
No full textThe inpatient room in hospital facilities has rules and standards but should be optimized with a creative spatial design approach, such as biophilic principles. The principles of biophilic consist of 14 patterns and are categorized into three criteria: nature in the space, natural analogues, and nature of the space with interior design consideration. The biophilic design approach is flexible, while the hospital facilities have standards that could limit the design exploration. This study aims to see the potential of biophilic principles in hospital design by young designers. This research was conducted by a design project and involved lecturers and design experts from the industry related. The method used was teaching in class and encouraging the creativity and activeness of participants by conducting studies individually and in groups. The main topics in class were enriched with biophilic material and design standards for hospital inpatient rooms set by the Ministry of Health of the Republic of Indonesia. Various results were found; there are 15 inpatient room designs, all with biophilic criteria based on students’ creativity. The design project successfully enhanced the creativity of biophilic criteria implemented in the inpatient room, although there are various constraints in hospital design standards

Measurements and Monitoring the Behaviour of Crossbeam in Orthotropic Bridge Deck with 3D Digital Image Correlation
No full textDigital Image Correlation is a cheap and easy to use measurement method that has been proved to characterise any solid material parameters up to plastic deformation range. The digital image correlation measurement system is based on the tracking of a collective number of pixels from the surface of the reference image to the deformed image. This summation of pixels is called subset. To achieve a reliable measurement in DIC, each of the subsets must contain sufficient speckle pixels. Therefore, there is a firm distinctive intensity pattern contained in a particular subset relative to other subsets. However, with the current DIC method, the user must rely on the intuition and experience for determining these number of speckle pixels. To investigate this problem, a study of measurement and monitoring the behaviour of crossbeam in Orthotropic Bridge due to in-plane quasi-static load is conducted. The reliability of DIC method on measuring strain and deformation in an elastic zone of a steel material is also examined and compared to the other measurement technique such as strain gauge and LVDT. Also, a finite element model is developed to estimate the strain and out-of-plane deformation at the certain location of the crossbeam.The study focuses on the specific location at the crossbeam with ‘haibach’ shape cope hole, where the strain concentration is expected to be significantly high. The applied quasi-static load is set until 250 kN, with strain gauges and LVDT are installed at the same side of the crossbeam (free edge side), and DIC is installed at the exact opposite side (inner side). Parallel with the test on the Orthotropic Deck Bridge specimen, several benchmarking test is also conducted. These tests are used to examine the problems encountered during the initial experiment.The study shows that owing to the quasi-static in-plane load, the crossbeam encounter an out-of-plane behaviour. Therefore, to achieve an accurate measurement, a 3-D DIC measurement system is obliged to use. Strain observed into two different directions: x and y-direction, gives different results in term of accuracy. Due to the low strain limit of DIC system, the result in x-direction can be considered as unreliable. For strain measurement in y-direction, some of the results exceeding the low limit strain of the equipment, give a close match result with the strain gauges, within the acceptable amount of deviation. For out-of-plane deformation, all the measurement show a good agreement between the DIC and LVDT technique. The average speckle pattern size that is used in this research is 0.2 mm, and an average area of 38 pixels2 for a particular speckle pattern. One of the benchmark study shows that under the same condition with same expected level of displacement, an average speckle pattern area between 36 and 45 pixels2 leads to reliable 3D measurement. The finite element model that has been developed in this study also gives close strain estimation for both x and y-direction, compared to the measurement data (DIC and strain gauges). <br/

Numerical Simulation of Deep-Sea Minings Plume Using Arbitrary, Non-Orthogonal Mesh
No full textIn recent years, the demand for minerals and rare-earth elements are escalating due to rapid technological advancements and developments. This condition raises the importance of Deep-Sea Mining (DSM) as an option to fulfill the global demands, for the sake of future ambitious projects. On the other hand, DSM still faces some drawbacks and obstacles in its operations, e.g. environmental impact of its tailings discharge. Thus, the presence of tools for predicting the behavior and environmental impact of DSM tailings becomes crucial for the sake of conducting sustainable DSM operations. Researches, both numerical and laboratory experiments, are then done to achieve this goal. In the study of DSM tailings behavior through numerical simulation, the challenge lies in the ability to implement the complex physics phenomena around DSM plumes to a numerical model. This research is thus aimed to observe one of the parts of the so-called physical phenomena, and numerical constraints on the simulation of DSM plumes: the effects of implementing arbitrary non-orthogonal mesh. Arbitrary non-orthogonal mesh would give users the freedom to refine the mesh based on the required resolution on a certain area in the simulation domain. In this research, an arbitrary non-orthogonal mesh is constructed forming a domain geometry of 3D tank with round pipe as a source of tailings discharge, adapting the laboratory setup of Byishimo (2018). Mesh refinement is done around the pipe discharge area, where the jet mainstream expected to occur, and near the bottom, where settling of solids fraction and high velocity-gradients are expected to occur. Top-hat approximation theory is then used for defining the inlet boundary condition of the simulation domain, and smooth solid wall is used for the bottom boundary. In observing the effect of arbitrary mesh, two parameters are varied: solids settling rate, and differentiation scheme. Following this, six simulation cases are prepared, containing three solids-settling conditions (minimum, realistic, and extreme solids fraction settling) and two differentiation schemes (Gauss Gamma and Gauss Linear). These cases are then simulated using the CFD drift-flux model in OpenFOAM for two incompressible fluids, with ambient fluid and tailings mixture as the two incompressible fluids. Turbulence is modeled using LES method, with Wall-Adapting Local Eddy-viscosity (WALE) LES model for modeling the subgrid-scale of the turbulence. Two simulated field variables are picked to be observed and compared with the laboratory measurement data: flow velocities and local Suspended Solids Concentration (SSC). Simulations show that the constructed domain able to generate stable results using not only Gauss Gamma differencing scheme but also Gauss Linear, which originally expected to give unbounded results. From simulations with various solids settling conditions, it is analyzed that the implementation of solids settling using the mentioned function leads to constant settling rate with inability to re-suspend the settled solids. Thus, simulation of cases with extreme solids settling leads to hyper-concentration of solids fraction in the cells on the bottom. The top-hat profile of the inlet boundary condition is constantly sustained throughout the simulation, resulting in uniform jet vertical velocity profile. The simulations also show that momentum-driven jet-like flow can be observed around the impingement point, while gravity current generated further from the impingement point. The simulation results show that the mesh refinement is enabling simulating and validating the flow with the required resolutions. Moreover, the constructed domain also shows that Gauss Linear can be used for simulating DSM plumes, furthermore using full tank domain. The simulated SSC also turns out not only affected by the simulation domain and mesh, but also the differencing scheme, and the presence of settling and pick-up functions.Offshore and Dredging Engineerin
