Introduction,imals. The development of this skill over the centuries has been fundamental to the growth of civilization. Mans early efforts to harness the power of wind and water owed very little to engineering science, and indeed the early steam engine was a practical reality . the science of thermodynamics was

The equations of heat conduction,e general form:.where . is the rate of heat conduction in the n-direction, and . is the temperature gradient in that direction. The partial derivative is used since there may exist temperature gradients in other directions. One-dimensional conduction does not often occur in practice since a body wou

Two-dimensional steady state conduction, of edge and corner effects which must be present in any finite object. The error involved in this neglect will depend on the dimensions of the system. Consider, for example, the wall of a building some 6 m long and 200 mm thick. In the absence of doors and windows, conduction through such a wall wi

Natural convection,ng it is another important example of convection. Fluid motion is due entirely to buoyancy forces arising from density variations in the fluid. There is often slight motion present from other causes; any effects of these random disturbances must be assumed negligible in an analysis of the process. N

Separated flow convection,e resulted in the rapid growth of the use of complex geometrical heat transfer surfaces, which have developed from the single tube and tube bank placed across the line of flow. A single tube or cylinder placed in a cross-flow is completely submerged in the fluid and it therefore forms an obstacle ar
