متن کاملHeat Transfer Coefficient, Two-Phase Flow Boiling of HFC134a
Experimental measurements of local heat tra nsfer coefficients and pressure drop are made for forced conv ection boiling and condensation for R134a-oil mixtures inside a horizontal tube. The results are compared with the experime ntal data of pure Rl34a. Average convection boiling and cond ensation heat transfer coefficients decreased about 20% at a 10\ o il mass fraction, and boiling and conde...
متن کاملExperimental measurement of heat transfer coefficient and mass of deposited CaSO4 in subcooled flow boiling condition
Fouling is a common, fundamental and costly problem in heat transfer systems, which reduces thermal efficiency of equipment, increases the energy loss and causes strong damage to the heat transfer equipment in various industries. The main causes of fouling on the heat transfer surfaces are salts with inverse temperature-solubility in the fluid which calcium sulfate is one of the most important ...
متن کاملUniversal approach to predicting heat transfer coefficient for condensing mini/micro-channel flow
A new universal approach to predicting the condensation heat transfer coefficient for mini/micro-channel flows is proposed that is capable of tackling many fluids with drastically different thermophysical properties and very broad ranges of all geometrical and flow parameters of practical interest. This is accomplished by first amassing a consolidated database consisting of 4045 data points fro...
