Transfer Properties

By using the FLUENT software, the flow and heat transfer properties of several elliptical tubes were numerically studied. The mathematical models of the tubes flow field were established. The implementation incorporated a SMPLE-based semi-implicit solution algorithm that was applied to iterating calculation. Results shows that the surface heat transfer coefficient, temperature difference between inlet and outlet were all higher than circular tube, when mass flux equal to at inlet of elliptical tubes and circular tube and wall temperature was invariable. Therefore, the elliptical tube is a kind of effective heat transfer enhancement element.

Transfer Properties

In the present paper, numerical study of flow and heat transfer properties of RP-3 kerosene at liquid and supercritical conditions in an impingement model is conducted with renormalization group (RNG) k−ε turbulence model and a ten-species surrogate of kerosene. The independence of grids is first studied, and the numerical results are compared with experimental data for validation. Characteristics of flow and heat transfer of kerosene flow in the impingement model are studied with different inlet mass flow rates and different inlet temperatures. The velocity and temperature field show similar profile compared to that of air impingement. The heat transfer rates increase first with the increasing of inlet temperature and then decrease suddenly when the inlet temperature is 500 K.

Effects Of Temperature

Various types of non-Newtonian behaviour are reviewed together with examples commonly encountered in industrial situations. The effect of such fluid properties on isothermal laminar flow in simple geometries is considered. Various problems in laminar heat transfer to non-Newtonian fluids are also discussed and the effects of temperature dependent rheological properties and viscous dissipation are considered. The relevance of these simple examples to more complex industrial problems is discussed.
