400), Unsteady asymmetric regime (400 < Re < 1000), Turbulent wake regime (Re > 1000). One of the most important but unsolved problem in the area of engineering and sciences are Turbulence. Solving the time dependent three-dimensional Navier stokes equation might give a complete description of turbulent flows but with the available computers are not capable enough to solve for the required length and time

But, in case of cardiovascular disease when there is an inefficient non-physiological flow, the blood flow vorticity may change. Such as, in ASD, the vortex rotation tends to be in the opposite direction than normal which causes increased dissipation of energy. Thus, such kind of hemodynamic observations greatly assist in the evaluation of different heart conditions

Experimental To be competitive as renewable energy recourse turbines in wave energy generation must be robust and economical for a number of years. Approaches utilize experiments to characterize and predict the effect of parameters involved. One of which is advancements to turbine blades due to unsteady hydrodynamic loads. Characterizing these loads can determine their fatigue life and determine a more reliable material to be used for manufacturing the blades avoiding premature failure. Reliability

(UDF) according to the log-law wind profile (Holmes 2015). The parameters used for inlet wind flow is represented in Table 3. The fluctuation of wind velocity at each time step is then generated by utilizing the vortex method by adding a fluctuating vorticity field to the specified mean velocity

two-dimensional contour of a rocket nozzle known as method of characteristics. Method of characteristics is mainly a technique for solving partial differential equations. Typically, it is used to solve first order partial differential equations, but in this thesis it is used to solve the velocity potential equation which is a partial differential equation of hyperbolic nature.

There are a large number of literatures available on the study conducted to improve the working of wind turbines. Some of these researches have been implemented practically while others are still in experimental phase. A literature was prepared by Md. Mahfouz Sarwar, Nazia Nawshin, Muhammad Ali Imam and Mohammad Mashudon on “A new approach to improve the performance of an existing small wind turbine by using Diffuser.” They have studied the improved effect of diffuser on the performance of a small
