Heat and Mass Transfer Analogy Studies of Binary Liquid Mixture in Comparisonwith Ethanol-n-heptane Evaporating to Air

摘要

An experimental and theoretical study of heat and mass transfer analogy and acomparison of that to a binary liquid mixture evaporation is presented. Common organic solvents, ethanol and n-heptane, were used to form an alcohol-hydrocarbon mixture. Heat transfer coefficients were measured with a copper plate resistor and mass transfer coefficients with a square pool. The heat and mass transfer analogy is presented for a system having two evaporating compounds with a fixed value of air flow and verified by measuring and comparing mass transfer
