CALCULATION OF CRITICAL REYNOLDS NUMBERS IN ROUND PIPES AND INFINITE CHANNELS AND HEAT TRANSFER IN TRANSITION REGIONS
摘要
Methods for calculating the critical Reynolds number in pipes and infinite channels are discussed according
to the modified Meisser's entropy principle that yield results in good coincidence with the experiments. Once
the critical Reynolds number is determined, interpolation polynomials are used to obtain friction factors and heat
transfer in the transition region. Comparison with the results of other investigators of transition region
phenomena seems to vindicate the above approach.
