CFD STUDY OF A MICRO AIR VEHICLE (MAV)
Full text linkMicro Air Vehicle (MAV) is new type of aircraft technology that is maturing day by day and have recently reached unprecedented levels of growth. MAV is small in size and provides enormous potential in many applications, both for military and civilian use. There are three types of MAV, namely rotary wing, flapping wing and fixed wing. Due to the small size, MAV faces difficulty to fly properly due to the atmospheric perturbations. This study aims to model a suitable fixed wing MAV using Computational Fluid Dynamics (CFD) to investigate the lift coefficient, drag coefficient and lift to drag ratio when MAV is used in pertubed flow conditions. When there is wind disturbance, the simulation results show that the lift and drag coefficient for several angle of attack changes. However, the lift to drag ratio seems unaffected. Results showed that MAV is best operated at 8° angle of attack as it provided the maximum lift to drag ratio for situations without and with the present of wind disturbances. The fluid dynamics behavior of flow around MAV are also discussed accordingly. Even though MAV is small in size, it is found that vortex or vorticity flow also exist in MAV, especially at high degree angle of attack
Characterization of Cotton Fiber Filled Polyvinyl Alcohol Films
No full textPetroleum based polymer films have high resistance toward degradation and bring about countless environmental problems where there are a lot of obstacles and restraint causes inadequacy of recycling, contributing to accumulation of terrific waste. To counter the low degradability of plastic waste, it can be conquered with the development of biopolymer by adding organic fibers, which makes the films to be more biodegradable. In this study, cotton fiber filled polyvinyl alcohol (PVA) films were prepared with various cotton fibers loading, which are 0, 5, 10, 15 and 20 wt. % in 20g, 25g and 30g of PVA. Fourier transform infrared spectroscopy analysis discovered that both cotton fiber and PVA were hydrophilic in nature and confirmed that there was no chemical interaction formed between cotton filler and PVA matrix.This study is aimed to highlight on the tensile properties, hardness and thermal stability of the PVA/Cotton fiber blended films. Moreover, the investigation on the surface morphology and surface fracture of the blended films were conducted by using scanning electron microscopy. Based on the result obtained, PVA/ Cotton blended films with higher cotton fiber loading demonstrated lower tensile strength and elongation at break due to the weak intermolecular bonding between the cotton fiber and the PVA matrix. However, the tensile modulus was improved gradually as the increment of cotton fiber loading those results in stiffer blended films as compared to pure PVA film. Hardness value of the PVA/Cotton fiber shows a significant boost when cotton fiber is added as filler into the PVA matrix as well. Besides, thermal stability of the blended films also shows a minute improvement as the cotton fiber loading increases
