Abstract:
The characteristics of heat transfer and fouling of sintered porous surface tube (SPST) heated electrically in NaCl solution were investigated. Mathematical model of heat transfer was constructed about Nusselt number, Reynolds number, Prandtl number and mass fraction of NaCl solution. The results show that sintered porous surface tubes have better properties of enhanced heat transfer than that of smooth surface tubes (SST) in NaCl solution. Furthermore, NaCl fouling won’t deposit on the surface of SPST as long as the mass fraction of solution is below the critical fouling mass fraction. The model can be used to predict the heat transfer coefficient of SPST in NaCl solution, which displays that results of simulation are in accordance with the experimental values.
