Experimental estimation of local heat flux on boiling surface in a mini-channel

Thermal characterization of a multi-turn pulsating heat pipe in microgravity conditions: Statistical approach to the local wall-to-fluid heat flux

“…Scammell et al [5] adopted a similar approach for the evaluation of the heat flux and the local heat transfer coefficient exchanged by a Taylor bubble passing through a tube, internally and externally coated with a polyimide tape. Farahani and Karami [6] proposed a different technique for the evaluation of the heat flux exchanged between the working fluid and a boiling surface, consisting in wall temperature measurements by means of thermocouples, therefore processed by means of an inverse problem resolution approach (conjugated gradient method).…”
