Explore the discretization of unsteady convection equations in this comprehensive 56-minute lecture. Delve into various numerical schemes including Central Difference Scheme (CDS), Upwind Difference Scheme (UDS), and Lax-Wendroff scheme. Examine higher-order schemes for convection, such as the Second-order upwind scheme, Beam Warming scheme, Fromm Scheme, and QUICK scheme. Gain a thorough understanding of the Finite Volume Method as applied to convection and diffusion problems, with a focus on the mathematical techniques used to solve these complex equations.
