Modeling experiment of flow and heat transfer in LNG tank by electrochemical method

Abstract

Heat and fluid flow in a horizontal layer is experimentally studied high Rayleigh number conditions by electrochemical mass transfer technique. The experiment simulates a LNG tank heated from the bottom and the sidewalls and cooled from the top surface. From the experiment, following results are obtained. When sidewalls are heated, the heat transfer along the bottom surface is reduced. Heat transfer along sidewalls is independent of bottom heating, and is modeled by an equation for laminar natural convection flow even for Ra>(10)^9.
