Abstract
The new similarity analysis method is applied to develop a novel system of analysis and transformation models of liquid laminar forced convection with consideration of variable physical properties. As an example, the formulated temperature-dependent equations on density, thermal conductivity, absolute viscosity of water, and specific heat are applied, and the reliable numerical solutions on water laminar forced convection are obtained for investigation of the coupled effect of these variable physical properties. Theoretical equations on heat transfer are obtained based on the new similarity model, where the wall dimensionless temperature gradient is the no-given variable. The system of key numerical solutions on the wall dimensionless temperature gradient is formulated by a curve-fitting approach. Combined with the formulated equations of the wall dimensionless temperature gradient, the theoretical equations on heat transfer become available for simple and reliable prediction of heat transfer of water laminar forced convection with consideration of coupled effect of the variable physical properties.
