Experimental data and model for heat transfer, in liquid falling film flow on shell-side, for spiral-wound LNG heat exchanger
A test plant has been constructed for measurements of local heat-transfer coefficients and frictional pressure drops on the shell-side of spiral-wound LNG heat exchangers. Measurements have been performed with single-phase vapor flow, liquid film flow and two-phase shear flow. This paper focuses on the measurements and the results from the liquid falling film flow experiments. One hundred and seventy-one liquid falling film heat-transfer measurements have been performed at a film Renumber range of 500-8000 with ethane, propane, methane/ethane mixture, ethane/propane mixtures and ethane/n-butane mixture as test fluids.
