Comparison of heat transfer in straight and corrugated minichannels with two-phase flow
Peukert, P. ; Hrubý, Jan
Measurements of heat transfer rates performed with an experimental condensation heat exchanger are reported for a corrugated minichannel tube and for a straight minichannel tube. The two cases were compared at same flow regimes. The corrugation appears advantageous for relatively low steam pressures and flow rates where much higher heat transfer rates were observed close to the steam entrance, thus allowing shortening the heat exchanger with the associated advantages of costs lowering and smaller built-up space. At high steam pressures and high flow rates both tubes performed similarly.
Experimental heat exchanger with a corrugated capillary tube
Peukert, Pavel ; Hrubý, Jan
The short article inform the reader about a experimental heat exchanger build and located at the Academy of sciences of the Czech republic. This set-up was launched during November 2009. Ther article further contain research argumentation, some details of the design and actual stage of the set-up (year-end 2009).
