Exact One-Dimensional Solutions,oblems are non-linear since the temperature field depends on the flow field. Nevertheless, exact solutions to certain simplified cases can easily be constructed. One of the objectives of this chapter is to develop an appreciation for the physical significance of each term in the equations of continu

BOUNDARY LAYER FLOW: APPLICATION TO EXTERNAL FLOW,ow and thermal fields. The . concept, first introduced by Prandtl in 1904, provides major simplifications. This concept is based on the notion that under special conditions certain terms in the governing equations are much smaller than others and therefore can be neglected without significantly

CONVECTION IN EXTERNAL TURBULENT FLOW, unsteady velocity fluctuations. This description by itself suggests that exact predictions cannot be determined, and that analysis of turbulent flows will not be easy. However intimidating turbulence may be, its importance is clear: turbulent flows are found in many industrial and natural processes

CONVECTION IN TURBULENT CHANNEL FLOW,ia for fully developed velocity and temperature profiles, and will focus most of our attention on analyzing fully developed flows. As in Chapter 6, our analysis is limited to general boundary conditions: (i) uniform surface temperature, and (ii) uniform surface heat flux.

CORRELATION EQUATIONS: FORCED AND FREE CONVECTION,ven after making many simplifying assumptions, analytical determination of . is generally not a simple mathematical problem. When complicating factors such as geometry, variable properties, turbulent flow, boiling, condensation, etc. are involved, the heat transfer coefficient is usually determined

Convection in Microchannels,ing methods for high heat flux components focused attention on the cooling features of microchannels. Microchannels are used in a variety of engineering and scientific applications. The inkjet printer is a classic example. Extensive use is found in medical applications and in micoelecro- mechanical
