fluid mechanicsfluid motionSummary Fluids with no viscosity, no surface tension and which are incompressible are called ideal fluids. Fluids with viscosity and surface tension, and which are compressible are called real fluids. This chapter discusses the four different types of fluid flow, namely ...

This chapter summarizes the basic concepts and equations of fluid mechanics. The traditional finite difference procedures are used in solving fluid flow problems. Different fluids show different relations between stress and the rate of deformation. Depending on the nature of relation followed between ...
