The diameter of the channels is varied within the heat exchanger based upon the simulation results of uniformly sized channels of the heat exchanger.
The geometry is then exported to ICEM CFD which is a meshing tool.
Experimental setup and Validation Experimental studies are conducted on a cross flow heat exchanger (radiator of a Maruthi Omni) to validate the results obtained from the numerical simulation.

There are known several methods for calculating and measuring of the aerodynamic variables – In-situ measurements, wind tunnel measurements, CFD simulations and calculations by national standards.
Compared to the other wind tunnels it is unique, because it has two test sections – the front and the back measuring space and thus it allows simulation of both uniform and turbulent flow.

A steady state simulation with pressure based solver is performed.
Comparison of both results shows the simulation well predicts the location of shock diamonds and bow shocks at the exit of the nozzle.

The model was incorporated into a CFD code that solves the Navier-Stokes equations with the standard k-ε closure turbulence model.
Moreover, the simulation revealed that the concentration and distribution of activated refiner particles in the sump can be controlled by varying the distance H.
The simulation with the model revealed that shortening of time needed for the activated refiner particles to transport from the cavitation zone to the solidification area could be the main reason for the improvement in ultrasonic refinement effects.

As for as the numerical simulations for flow and convection heat transfer of nanofluids is concerned, only very recently a few papers have published.
In this study, the forced flow and convective heat transfer of the laminar flow containing EG/water based nanofluids under constant heat flux is simulated using the Computational Fluid Dynamics (CFD) tools.
