flat plate

Understanding the mechanics of a turbulent boundary layer is important, since in most practical problems it is the turbulent boundary layer that is primarily responsible for the surface shear force or surface resistance. The velocity distribution in a turbulent boundary layer on a flat plate is considered parallel to the flow. It is important to know the correlations between the boundary layer thickness and shear stress. Therefore, the problem of controlling the flow in a boundary layer on a flat plate is one of the important problems of boundary layer mechanics.

In fluid and gas mechanics, a subject that has been the focus of considerable scholarly attention is the modeling of flow phenomena on streamlined surfaces. These surfaces, which are typically installed in a parallel orientation to the direction of the free stream, play a pivotal role in the study of fluid dynamics. The boundary layer theory represents a pivotal branch of fluid dynamics, given the airflow plate is characterized by a high Reynolds number of airflow velocity entering the plate's plane surface contexts.
