Lid Driven Cavity Flow. - Implemented Artificial Compressibility Method for Pressure-Velocity coupling with 4th order Runge-Kutta time stepping. Such type of arrangement can set up a single circulation in the upper layer in the system. Finally, optimized CUDA codes for the lid-driven cavity were developed and run on a PC with a 2. Finally, in Section 6, the direction of research for the master thesis project is given. Sarfi, 2D Lid Driven Cavity Flow using SIMPLE algorithm, MathWorks, (2018).
