EXPERIMENTAL AND THEORETICAL INVESTIGATIONS ON THE STEADY-STATE AND TRANSIENT-BEHAVIOR OF A THERMOSIPHON WITH THROUGHFLOW IN A FIGURE-OF-8 LOOP
MetadataShow full item record
This paper deals with experimental and theoretical investigations on a thermosyphon with throughflow in a figure-of-eight loop. The one-dimensional energy and momentum conservation equations are solved with suitable assumptions and analytical solutions are obtained for the steady-state case for different throughflow inlet and outlet points. The steady-state flow rates obtained with hot and cold leg injections are compared. Comparison of predicted steady-state flow rates with experimental data shows agreement within +/- 15%. The transient behaviour has been obtained numerically using the finite difference method and compared with experimental data.
