Özet

In this study, the time dependent heating of a solid cylindrical body replaced within an isolated cylindrical container and reciprocally the simultaneous heating of the fluid (air/water) inside the container is experimentally investigated. For this purpose a double-walled cylindirical container of 25 cm diameter is prepared and isolated by using a 2 cm thick layer of styropor between the walls. An aluminium cylinder heated within some other adiabatic media then placed coaxially inside this container. Heat transfer problem socreated is assumed to be axially symmetric and accordingly the temperature measurements are taken at five stations on three horizontal straight lines all chosen to be on the same vertical plane passing through the common axis. At the end of the study, the following results were obtained: i) The equilibrium state between metal and fluid was reached in 120 min in air environment and 25 min in water environment. ii) It has been found that the cooling rate of the metal in the aqueous environment is approximately 5 times faster than the air environment. iii) The cooling and warming speed was faster in the first 30 min in the air environment and in the first 5 min in the water environment compared to the other time periods.
