Computational challenges in numerical simulations of stably stratified flows

• Date: 3. 3. 2022

• Room: K3
• Speaker: Tomáš Bodnár

The stratified flows are common physical phenomena typically found in many environmental and industrial problems. Although being studied for many decades and centuries, new problems associated with their solution by means of high resolution numerical methods arise in simulations of related practical problems. The talk will focus on some issues found while solving the wall bounded stably stratified flows under a range of Froude and Reynolds numbers. The problems of choice of suitable numerical methods, computational setup and selection of soft boundary conditions on artificial boundaries will be discussed in detail. Selected results of stably stratified flow over a 3D hill will be presented to demonstrate the main points of the talk.
