A parabolic solar dish concentrator, as the heat source of an organic Rankine cycle (ORC), can be used for power generation.Different types of tubular cavity receivers with different nanofluids can be considered for use in the solar dish collector to improve its efficiency.In the current research, an ORC with three different cavity receivers includ
