Initially, the front surface of a cubic volume of the opening to the environment has become a cubic volume of cavity in the top and bottom surfaces cooled by natural convection laminar boundary conditions that have been examined in experimental and theoretical case. Numerical analysis was completed by using the Fluent (CFD) software; and experimental results were compared.
A conditioning chamber in this experimental study 2x2x1,8m size to provide the natural convection conditions are included in the application. Also the inlet of the experimental setup is given to the conditioning room. Finally, in this work, temperature change, velocity and current function chart were obtained. In addition to time-dependent change of the Nusselt number were obtained as a result of theoretical and experimental studies.
Key words: Natural convection, Laminar flow, Open cavity, Rectangular cavity.
