Abstract:In order to better study natural convection heat transfer phenomena of horizontal circular cylinders in large space, a testing system was designed and implemented. The testing system used a mode of upper and lower computer, and finished the measurement of heat transfer coefficient and verification of criterion expression. The actual application results show that the system can obtain full feature, higher precision and better repeatability, and better satisfy the requirements of natural convection heat transfer testing.
Key words:horizontal circular cylinder;natural convection heat transfer;testing system
