The current work develops a general purpose Navier-Stokes semi implicit solver capable of handling three-dimensional unstructured grids. The ow needs to be laminar and incompressible. Species transport equation can also be solved using a segregated algorithm. Pressure Poisson equation that takes most of the solving time has been parallelized using CUDA programming language on GPU, with Algebraic Multigrid for orthogonal unstructured grids. Domain decomposition has been done using greedy colouring method. Single phase jets have been studied in presence of walls has been studied, which is of interest in Internal Combustion engines. Large Eddy simulation (LES) modeling has been employed for simulating turbulent ows using Static Smagrosnky model. Validations have been presented for turbulent round and plane jets. Laminar and turbulent coaxial jets for different velocity ratios for has been simulated and the effect of faster annular jet on the core of inner jet is analyzed and presented.
