. Drag force. The surrounding fluid exerts pressure forces and viscous forces on an object. .. The components of the resultant force acting on the object immersed in the fluid are the drag force and the lift force. .

In a flow, the boundary layer represents a (relatively) thin layer of fluid that is nearest the solid boundary. 87-351 Fluid Mechanics. [ physical interpretation: what are we doing today? ]. The behaviour of the boundary layer is very different from that of the fluid above it.

Johnson Created August 2007 updated March 10 2010 Abstract This note is intended as a brief introduction to the theory and practice of perfectly matched layer PML absorbing boundaries for wave equa tions intended for future use in the course
Convection in the boundary layer occurs to transport heat moisture, and momentum from surface to free atmosphere. Two common scenarios:. 1) Daytime solar heating 2) cold-air outbreaks, lake effect.
