Dependency of pure liquid pool boiling heat transfer coefficient to bubble contact angle on roughened Brass heater in new model
Abstract: Heat transfer coefficient of nucleate pool boiling Nucleation is a basic part of phase transformations, which plays an important role in understanding and describing any phase change processes. For a boiling process, nucleation appears in the initial stage, and directly affects bubble formation and boiling intensity. According to the heterophase fluctuations which induce phase transition, the phase change has two main types. Classically, phase change caused by the fluctuation with …

Optimization of Procedure and Variables of a Double Pipe Composite Heat Exchanger with Protruding Surfaces
Abstract: Under low heat duty conditions, double pipe heat exchangers are employed. When utilized for heavy-duty tasks, they show limitations. To use double pipe heat exchangers for heavy-duty applications, heat transmission needs to be increased. In this project, we are investigating the optimization process parameters of a twin pipe heat exchanger with and without protruding surfaces. In both cases, the inner and outer tubes are composed of steel, and the working …
