INTRODUCTION The main objective of this assignment is to simulate a 3-D air flow in a pipe using Ansys CFX. The pipe was simulated under specific conditions. These conditions are air temperature to be 25⁰C (degrees Celsius)‚ one atmospheric reference pressure‚ no heat transfer and laminar flow. The results from the simulation of laminar flow in the pipe were compared with the theoretical ones. Also the mesh was refined in the simulation to see if it is possible to get more accurate results using grid

This load is applied to the FE model in ANSYS‚ and boundary conditions are applied according to the engine mounting conditions. The analysis is done for finding critical location in crankshaft. Stress variation over the engine cycle and the effect of torsion and bending load in the analysis are investigated. Von-mises stress is calculated using theoretically and FEA software ANSYS.

The solver is using a full-scale time-marching 3D viscous model. Underlying equations‚ three dimensional Navier-Stokes equations in their conservation form‚ are being solved by using a Finite Volume method‚ where equations are integrated over the finite control volumes. Thereby‚ the solution domain is subdivided
