Abstract:

Fundamental equations of conservation of mass, momentum, and energy are applied to the problem of heat transmission by forced convection from a line combustion source. The influence of atmospheric stability and surface roughness on growth of the heated zone, decay of temperature from the heat source, and aerodynamic drag is presented. Theory presents groupings of the variables that are common to heat transfer and fluid flow problems concerning the surface air layer. Results reveal that atmospheric stability plays an important role in the growth of the heated region, decay of temperature, and aerodynamic drag for small values of friction velocity and macroviscosity parameter. For large values of these parameters large surface roughness, atmospheric stability is not important. Author
