Summary:

In this project fluid flow and heat transfer in two-dimensional micro channels are studied numerically. A computer code based on Lattice Boltzmann Method (LBM) is developed for this purpose. The code is developed using MATLAB and Jacket software and has the important feature of being able to run parallel on Graphics Processing Units GPU). The code is used to simulate flow and heat transfer inside micro and macro channels. Obtained velocity profiles and Nusselt numbers are compared with the Navier-Stokes based analytical and numerical results available in the literature and good matches are observed. Slip velocity and temperature jump boundary conditions are used for the micro channel simulations with Knudsen number values covering the slip flow regime. Speed of the parallel version of the developed code running on a GPU is compared with that of the serial running CPU version and for large enough meshes more than 10 times speed up is reported.
