ANSYS ANALYSIS OF VORTEX ENHANCED LAMINAR FLOW MIXING OF DIFFERENT FLUIDS Mrs. SUBHASMITA PADHI & Prof. VINAL G VIRANI Department of Mechanical Engineering, School of Engineering, RK University, Rajkot, Gujarat, India ABSTRACT This report presents an overview of available knowledge, literature and research regarding the different flow mixing mechanisms and their characteristics. It covers existing literature related to vortex flow, it’s properties and applications, potential application of Helmholtz’s theorem, numerical and investigation on fluid mixing behaviour in flow with different combinations of vortex. In many engineering applications where ever mixing of the two or more fluid stream are achieved, it is desired to have shorter mixing length. Higher turbulence level is one mechanism to achieve shorter flow mixing length. But total pressure loss associated with higher turbulence is crucial and undesired. In present work, it is tried to achieve the stream wise mixing of different fluid with the help of various vortex systems. In this approach it is found that local intense

turbulence intensity is low and hence lead to lower total pressure drop.
INTRODUCTION The Fundamental of a vortex is widely used in fluid dynamics. Those who do take closer look quickly realize the difficulty of defining vortices equivocal. When the numerical simulation of fluids is recently common in the special effects on industry, here highly turbulent phenomena such as explosions are remained challenging. It is difficult to analysed that effects also on the high-resolution grids. Difficulties associated were with the vortex prolong term. Solving the standard velocity and pressure form of the Navier-Stokes. when all these difficulties decrease, the cost of numerical dissipation and proposed coupling are increase. ANSYS are mostly used for the modelling and simulation of any mechanical component to identify/predict the optimum working conditions where efficiency can be stablised or improved.
LITERATURE REVIEW
Ravikant Sahu, Eklabya Gupta, Deepak Kumar Dewangan, Prakash Ku- mar Sen have done efficiency of a well-designed turbine is higher than the efficiency of a compressor, and the design process is often much simpler. The main reason for this fact, as discussed in compressor design, is that the fluid undergoes a pressure rise in the compressor. It is much more difficult to arrange for an efficient deceleration of flow than it is to obtain an efficient acceleration.[13]
B. M. Cetegen et al, in this paper the instability mechanisms and mixing enhancement arising from the interaction of a compressible vortex ring with a normal shock wave were studied in a colinear, dual-shock
