2D Fluid Flow Around a Plate: Consistent Analytical, Numerical and Laboratory Investigations
Chashechkin Y. D., Zagumennyi I. V.
Abstract:
Flow patterns around a horizontal plate were calculated numerically based on the fundamental set of equations and studied experimentally in a tank with stratified brine. Four types of fluids were studied including strong and weakly stratified, potentially and actually homogeneous ones. Linear model for internal wave generation by a strip sliding along underlying surface oriented at an arbitrary angle to horizon is investigated analytically. Both large scale (internal waves, wake and vortices) and fine flow components are studied, as well as flow structure and dynamics in a wide range of flow parameters including diffusion induced and transient vortex regimes at 0 < Re < 105.
Keywords:
