An Optimized Design of Solar Burner Through Thermal and Structural Analysis of Plate and Coil of Burner using ANSYS.

Résumé fourni par la source

This paper presents an optimized design of a solar burner using the finite element package ANSYS ® . Due to high conduction properties, copper metal has been used for both the coil and plate. The1.22 W pump power has been required for circulating oil in the circuit. Different cases for thermal and structural analysis of the plate and coil have been used in varying thickness of the plate for both in the case of heat removal and in the absence of heat removal. In each case, the temperature of the oil at the coil inlet has been taken as 270 C. In absence of heat removal of 30kW/m 2 the oil leaves the coil at 165 C while in the case of heat removal the oil leaves at a temperature of 144.3 C. In absence of heat removal the deformation produced in 5 mm, 1 cm, 1.5 cm and 2 cm thick plates have been observed as 0.859 mm, 0.472 mm, 0.3 mm and 0.223 mm, respectively. The Von Mises stresses observed are 557 MPa, 546 MPa and 536 MPa for 5 mm, 1 cm, 1.5 cm and 2 cm thickness of the plate, respectively. In the case of heat removal, the deformation in 2mm, 5 mm, and 1 cm thick plates come out to be 0.0682 mm, 0.086 mm and 0.138 mm, respectively. The Von Mises stresses for these thicknesses are 561 MPa, 487 MPa, and 477 MPa, respectively. The optimum plate thickness is found to be 5 mm. It is best suited for use in the burner from a thermal as well as structural point of view.
