WebJan 17, 2024 · Boundary layers are far better described using so called higher order moments, such displacement thickness (delta*=delta1), momentum thickness (theta=delta2) and energy thickness (delta**=delta3). WebThen the governing equilibrium equations of mass and momentum conservation are solved (Fig. 1 b) and the information (velocity, ... Since the sliding zone is relatively thin in thickness (10–20 cm), the defined contact surface was selected to establish the sliding surface, where a frictional contact algorithm is implemented. ... displacement ...
