Kinematic Simulation and Structure Analysis of a Morphing Flap
No full textThis thesis presents a study on the design and analysis of a morphing flap
structure integrated with actuation mechanism for potential application to large
aircraft. Unlike the conventional rigid flap mounted on the wing trailing edge,
the morphing flap is designed as a unitized structural system integrated with
three primary components: the upper and lower flexible skins reinforced by
stringers, an eccentric beam actuation mechanism (EBAM) with discs fixed on it,
and the connection of the discs with the stringers. Based on the EBAM concept
proposed by Dr Guo in previous research [1], the current study has been
focused on the EBAM design and optimization, kinematic simulation and
structural modelling of the morphing flap.
Although a lot of efforts have been made to develop the morphing flap in
previous research, it is lack of detailed design of the disc-skin linkage and clear
view on the mechanism optimization in relation to the shape requirement. The
main objective of this research is to meet the morphing shape requirements and
calculate the actuation torque for a specified morphing flap. Firstly effort was
made to design and optimize the disc shape and locations in the EBAM for the
best matching of the specified morphing shape with minimum actuation torque
demand. It is found that minimum three discs are required and their locations
have little effect on the actuation torque. Secondly attention was focused on
designs of the disc and a C-linkage with the stringers. To ensure that the C-
linkage works in practice, a twisted stringer flange design was proposed. Thirdly
the actuation mechanism was integrated with the stiffened skin to play the role
of an active rib in the flap structure. Based on the design, FE modelling and
analysis of the morphing flap structure was carried out. The behaviour of the
morphing flap under the internal actuation and external aerodynamic load was
applied for stress analysis and detailed design of the structures. Finally the
kinematics of the integrated morphing flap was simulated by using CATIA to
demonstrate the feasibility and the effectiveness of the improved design

Heat transfer and fluid flow in a water-filled glass louver subject to solar irradiation
No full textNumerical studies of fluid flow and heat transfer in a water-filled prismatic glass louver have been carried out to investigate the efficiency of solar thermal energy harvest via the proposed louver that could be deployed in buildings to improve natural lighting to save electrical bills as well as to harvest and store solar energy into thermal energy. One surface of the prismatic louver is adjusted to face the direct solar irradiation. Both direct and diffuse irradiations are incorporated for different air mass models. The distribution of absorbed solar radiation in the louver is pre-calculated via the Monte Carlo method and input as the heating source. The finite element method based on COMSOL is adopted to simulate the three-dimensional steady-state fluid flow and conjugate heat transfer in the triangular water channel. Temperature-dependence of water property is considered. The prismatic louver is surrounded by ambient air. Emphasis is placed on investigating the effects of flow rate and solar irradiation conditions on water temperature rise and energy harvest. It is found that the outlet water temperature is a strong function of the water flow rate. Most of the absorbed solar energy in the glass can be converted into stored thermal energy in the water through convective heat transfer. The water pumping power consumed is negligible as compared to the energy harvested. When the louver is adjusted to face the direct solar irradiation and the water flow velocity is 0.1 m/s, the overall utilization efficiency of the louver reaches 89.2, 90.3, 89.1, and 87.9% for AM1.0, 1.5, 2.0, and 3.0, respectively.Peer reviewe
