摘要: ABSTRACTThis paper analyzes results concerning flow boiling heat transfer in two parallel, asymmetrically heated vertical minichannels. The heating element for FC-72 Fluorinert flowing the minichannels was a thin foil with an enhanced surface on side contact fluid. In one minichannel, changes temperature smooth of were monitored using liquid crystal thermography. Changes outer glass minichannel and other observed infrared coefficient at foil–fluid interface calculated basis one- two-dimensional models. method, distribution determined by solving inverse conduction problem. governing equations solved finite-element method combined Trefftz functions used as shape functions. mea...
