In this we have compared our results with CFD software packages with classical formula and made an attempt to determine optimum cone angle.

In order to find out optimum angle at which head loss will be minimum different angle has been consider for the gradual contraction ratio 2. The experimentation was carried out to measure discharge (Q) at different pressure, from which inlet and outlet velocity was calculated. With the help of inlet and outlet velocity head loss has been calculated.Fluent software was used to plot the characteristics of the flow & GAMBIT was used design the model.

Every vehicle that uses an internal combustion engine requires at least one connecting rod .From the viewpoint of functionality, connecting rods must have the highest possible rigidity at the lowest weight. The major stress induced in the connecting rod is a combination of axial and bending stresses in operation. The axial stresses are produced due to cylinder gas pressure (compressive only) and the inertia force arising in account of reciprocating action (both tensile as well as compressive), where as bending stresses are caused due to the centrifugal effects. The result of which is, the maximum stresses are developed at the fillet section of the big and the small end.Hence, the paper deals with the stress analysis of connecting rod by Finite Element Method using Pro/E Wildfire 4.0 and ANSYS WORKBENCH 11.0 software. The comparison and verification of the results obtained in FEA is done experimentally by the method of Photo elasticity(Optical Method). The method of Photoelasticity includes the casting of Photoelastic sheet using Resin AY103 and Hardner HY951, preparation of the model from Photoelastic sheet calibration of the sheet to determine material fringe value.
