Résumé

A study of two-phase flow and heat transfer in a mini tube has been conducted experimentally. R134a has been used as the working fluid. This paper presents experimental results on boiling and condensation heat transfer coefficient in rectangular and rectangular grooved mini channels which hydraulic diameters of 0.81 and 0.64 mm, respectively. The boiling and condensation heat transfer coefficients were measured for saturated condition of R134a flowing in the horizontally placed mini channel tube. Length of the mini channel tube is 852 mm and it was heated or cooled by the water that flows through the upper and lower side of the mini channel tube. Wall temperature was measured by 24 thermocouples embedded in the tube surface. The boiling and condensation heat transfer in the mini channel has been measured over mass flux of 50,100,200 kg/m2s respectively. The measured heat flux is 2 to 10 kw/m2 for boiling and 1.5 to 9 kw/m2 for condensation test.
