This Master Thesis is concerned with the transient simulation of microburst or wind shear, a metrological event which had been the cause of many aviation accidents. This thesis work is known for the validation and verification of the microburst of 2D and 3D simulation of microburst with numerical solution by using the computational fluid dynamics. By considering these factors, the thesis is progressed with the validation process; the numerical solutions are verified with various experimental solutions to affirm their accuracy and applicability. Then the s imulated steady velocity profiles and characteristics of microburst are analyzed and compared with the time-averaged data obtained from the experiments. By the use of simulated data, more insights on the entire formation process and the adverse effects caused by the wind shear would be revealed. It also contains the animation of the respective verification process, shows how the profile fully developed with flow under the certain conditions. The flows with respective velocity forms the microburst under stipulated conditions are analyzed with various experiments under different conditions. The obtained result data would useful for the generating the wind shear simulation for the pilot training in parallel research.
