Abstract :
Use of dimensionless numbers for expressing experimental results in forced convection is irrational since the independent variables are transformed into interdependent in dimensional analysis. Nusselt number expressed in terms of Reynolds and Prandtl numbers is found to give effect of tube diameter and specific heat in erratic manner. Correlations are presented for gases and liquids in terms of measured variables by avoiding the use of dimensionless numbers. Heat transfer mechanism is discussed.
