Mixed flow pump impeller is a centrifugal pump device where the transition of fluid flow takes place in both axial and radial direction. In this work a mixed flow pump impeller has been designed using CATIA V5 software tool and analyzed using the fundamentals of fluid mechanics and turbo machinery. As per many researchers there are many methods are used to design the impeller but still the optimized design of the mixed flow pump impeller blade has been a cumbersome work. The impeller blades have been designed by varying the semi-cone angle. The CFD analysis is the advanced tool used in pump industry to improve the efficiency hence the CFD analysis is carried over the model to predict analytical values and to solve problems the problems that involves the fluid flow using ANSYS workbench 16.0. Because of its anti-corrosive property stainless steel is used as material for impeller and water (liquid) used as a fluent which flow around the impeller. From the CFD analysis the velocity and pressure in the outlet is predicted. The outlet values will be useful for calculating the efficiency of the pump.

This paper presents some experimental investigations to study the air flo w patterns on the headligh t domes of different two wheelers (HERO HONDA PASSION PLUS and BAJAJ PULSA R) wh ich influence the sta bility of the vehicle. The pressure distribution over the surface of the profile and the drag force are to be determined for various headlight dome orientations . This study helps in suggesting the suitable headlight dome profile that may reduce the drag force and effect of turbulence which in turn leads to the increase of vehic le stability. The results obtained during the simulat ion are to be validated by conducting the experiments on the scale down model of the headlight dome of HERO HONDA PASSION PLUS using Wind Tunnel test rig. The Co mputational Fluid Dynamics (CFD) tool was used to simu late the air flow pattern on the headlight dome in which boundary layer separation doesn't exist. The results obtained from the simulation are to be co mpared with the experimental results from the wind tunnel and the variation is to be found and that should be in the acceptable limit.
