Abstract
An experimental investigation of the effect of mixture of ethanol-methanol as a binary working fluid with pure fluid on thermosyphon performance is being presented in this project. The thermosyphon has main three components, an evaporator with a boiling enhancement structure, adiabatic section at the center and condenser. Experiment has been done to assess the effects of binary fluid and pure fluid on the performance of the thermosyphon at different inclination. The selected thermosyphon has one in 25.4 mm diameter and 500 mm length designed to dissipate 240 watt heat from the applying. The working fluid will be pure ethanol, pure methanol and mixture of both in (60-40) % by volume and filled by 60% of evaporator section. The method tested by applying heat load to the thermosyphon by four band heater of sixty watt capability as per application and also the condenser section is cooled by vessel with fluid pump and flow control arrangement. The testing of the thermosyphon has done at inclination of 90°, 75°, 60°, 45°, 30° and 15° with respective horizontal axis to study the effect on heat transfer ability of the system. The Properties of Pure Ethanol and Methanol and its (60-40) % mixture are studied and find out maximum heat input for various mixtures by heat transfer limitations correlations. So, heat input of 240 W is supply to evaporator region of 60 % FR. It found the result from the experimental trial is that ethanol fuels (60-40) the mixture proportion of binary fluid offers higher performance of thermosyphon than alternative mixture, at optimum mass flow rate and optimum angle inclination.
