Sep 15 2016 · FLUID FLOW A fluid is a substance that continually deforms (flows) under an applied shear stress. Fluids are a subset of the phases of matter and include liquids gases. Fluid flow may be defined as the flow of substances that do not permanently resist distortion The subject of fluid flow can be divided into fluid static s and fluid dynamics 14.

The faster the fluid motion the greater the convection heat transfer. In the absence of any bulk fluid motion heat transfer between a solid surface and the adjacent fluid is by pure conduction. The presence of bulk motion of the fluid enhances the heat transfer between the solid surface and the fluid but it also complicates the determination

Convection involves the transfer of heat by the motion and mixing of "macroscopic" portions of a fluid (that is the flow of a fluid past a solid boundary). The term natural convection is used if this motion and mixing is caused by density variations resulting from temperature differences within the fluid.
