Investigation of two phase heat transfer and pressure drop of propane in a vertical circular minichannel

Two-Phase Flow Boiling and Condensation Heat Transfer Characteristics of Natural Refrigerants: Review

“…The newly developed correlation for pressure drop based on the Lockhart-Martinelli method showed the mean deviation of 10.84%. Maqbool et al 41 presented heat transfer coe±cient and pressure drop of propane in a vertical circular minichannel. The heat transfer coe±cients increased with increase of heat°ux and saturation temperature, while the in°uence of mass°ux and vapor quality was found to be insigni¯cant.…”

“…Studies on the hydrocarbon mixture and comparison of several hydrocarbons with conventional refrigerants, such as R134a and R22 have been performed. The studies on the boiling heat transfer characteristics of propane (R290) were performed by Fernando et al, 38 Pamitran et al, 39 Choi et al, 40 Maqbool et al, 41 and Wang et al 42 Fernando et al 38 measured heat transfer coe±cients of propane in a vertically mounted multi-port minichannel heat exchanger. The heat transfer coe±cients increased with increase of heat°ux and mass°ux.…”

Heat Transfer Correlations for Elongated Bubbly Flow in Flow Boiling Micro/Minichannels

“…In this study, we only focus on flow boiling characteristics in single micro/minichannels instead of parallel or multiple micro/minichannels. Table 1 [21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37] summaries experimental flow boiling investigations in single small tubes. A micro/minichannel database was obtained by only selecting those data points which are located in the region:…”

Condensing two-phase pressure drop and heat transfer coefficient of propane in a horizontal multiport mini-channel tube: Experimental measurements

“…Several different studies can also be found in the literature working with natural hydrocarbons in macro-channels (Gebauer et al, 2013;Jung et al, 2004;Lee and Son, 2010;Lee et al, 2006;Garimella, 2015, 2016;Park et al, 2008;Thonon, 2008a), but only a few experimental studies deal with minichannels Fernando et al, 2008;Maqbool et al, 2013;Wen and Ho, 2009;Wen et al, 2006).…”
