title = "Optimization of heat flux distribution on dual parabolic dish for Stirling engine applications",
abstract = "This research giving up new concept for heat flux distribution improvement to SOLO 161 Stirling engine receiver. Stirling engine receiver need some stable heat flux, so the system could operate optimally until 9-10 kWel. Eurodish system operated stirling engine with single parabolic dish, located above the parabolic reflector. This paper developed a new design using dual parabolic dish with Gregorian method in order to be able place the Stirling engine below the parabolic reflector or on the ground. Geometry design from dual parabolic used mathematical calculations with intersecting line method done with Delphi software. The heat flux were evenly distributed with receiver diameter of 0.272 m could be achieved with parabolic design with primary diameter of 8.65 m and secondary diameter of 2.67 m with rim angle 71°. The geometrical calculations were verified by simulations using Geogebra software. We used solar ray tracing simulations from SolTrace software, were acquiring the optimal peak and average of heat flux are 1608 kW/m2 and 660 kW/m2 when the DNI 1100 W/m2.",
