Solar energy can be collected and used in a large variety of ways including: passive daylighting,heating liquids and gasses, or generating electricity. Additionally, many energy sources such as wind,biomass, hydroelectricity, and even fossil fuels originate from the energy provided by the sun.Parabolic solar concentration systems are state-of-the-art or mature technology. Parabolic-troughsolar concentrating systems are parabolic-shaped collectors made of reflecting materials. Thecollectors reflect incident solar radiation onto its focal line toward a receiver that absorbsconcentrated solar energy to raise the temperature of the fluid inside it. The heat transfer fromsmooth surface to fluid is smaller since the fluid is mostly laminar. The PTC receptor with glasscovering tube, conduction, convection, and radiation comprises three types of heat transfer. Artificialrawness is added to improve heat transfer, which disrupts and turbulently disturbs flow and therebyincreases a turbulent flow rate. The fluid, geometry, and roughness of the container surfaces arehighly dependent upon this transfer. The study uses three distinct types of artificial roughness, i.e., C,V-shape, and reverse L-shape. C-shape, V-shape. The research is performed under constant stateconditions by using computational fluid dynamics in the ANSYS CFX software and the CAD model isbuilt with a Creo model kit. For analyzing i.e., 005 kg/s, 010 kg/s, and 015 kg/s and Nusselt number vsmass flow curves are called three different mass flow rate considerations. The results havedemonstrated a significant increase in the rate of heat transfer with artificial roughness. With reverseL artificial roughness, the maximum heat transfer increase is observed.
