Experimental and numerical study of two 20 ° angled solar collectors. The solar collector is operated in the 4th floor of the Mechanical Engineering Masters Building, University of North Sumatra, with the working principle that the radiation entering the solar collector will heat the absorber plate further with the help of the natural convection optimum air temperature on the absorber plate will make the temperature the collector’s room goes up. Data obtained from experimental measurements are then analyzed or validated using CFD software. The assumptions used in CFD simulations include: steady, incompressible conditions, k-epsilon flow, and models made in the form of 3-D, as well as giving boundary conditions to the object to be analyzed. The purpose of this numerical study is to analyze and study: temperature distribution and fluid flow numerically on the surface of the absorber plate. Based on the simulation results, conclusions are drawn both on temperature distribution and fluid flow according to the recording of results at the time of measurement.
