It became one of the fastest-growing renewable energy resources in electricity generation. The wind power Horizontal axis wind turbine (HAWT) is proportional to the swept area. A multi-rotor can increase the area of the wind turbine in an array or a large diameter of a single rotor. Rotor sizes are continuously expanding with mature technology. In this research, a study was carried out to describe the flow simulation of a two-rotor, three-blade, ducted horizontal-axis wind turbine to evaluate its performance. The coefficient of performance increased by converging channels with convergence angles of 20° and 12°, respectively, because convergent ducts cause an increase in wind speed. DMRWT simulation and numerical analysis by MATLAB and ANSYS FLUENT. Both approaches presented good results.eninfo:eu-repo/semantics/closedAccessducted dual rotorconvergent multi-rotor wind turbine (CMRWT)horizontal axis wind turbine (HAWT)MATLABWind turbineArticle10.37934/cfdl.17.9.1451621791451622-s2.0-105003276500Q2
