Literature Review on Condensation Analysis of Flow Inside an Inclined Tube

Inclined tube influences the pressure drop and heat transfer coefficient by considerably affecting the flow pattern of fluid passing through it. In order to analyze the exact effect of inclination angle, various literatures have been studied and represented in the present paper. Different experimental analysis as well as different theoretical models developed in past are listed here for the same purpose. The paper thus is divided in three parts; first part gives the study of condensation of different vapors in horizontal tube and vertical tube followed by second part which includes development of two phase flow with different types of flow and finally the third part takes into account the effect of inclined tube on condensation heat transfer coefficient. The theoretical models developed so far have some limitation which needs to be studied before concluding the effect of inclination angle on the pressure drop and finally on the heat transfer coefficient.
