Özet
In this study, the heat transfer from a surface heated with constant heat flux to an oscillating vertical annular liquid column having a liquid-air interface with the atmosphere is investigated experimentally and theoretically using control volume approach. In the experiment, the reciprocating motion of water column is created using a piston cylinder mechanism and the temperatures are measured on the setup. For oscillating flow, using the control volume approach, mass, momentum and energy conservation equations are written and simplified to obtain appropriate governing equations and solved by Runge-Kutta method. Temperatures at specified points are calculated by using the mathematical model developed based on experimental parameters. Comparison of theoretical results with experimental data is shown to be in good agreement. A simple mathematical model is developed to estimate the temperatures in liquid column.
