The main objective of this work is to design a concentric three-cylinder heat exchanger for better heat movement, using a sum of four expansions to verify its hot presentation under similar boundary conditions. For this reason, the second creep condition is specified for robust dividers where the heat flow for the outer side divider is concentrated to achieve an adiabatic state while the dividers and inner vanes of the cylinder are coupled. The deltas for the outside and inside of the line are characterized as mass flow trees; The power source is marked as an outlet with a pressure factor. Flow programming is used to determine the movement of liquid and heat flow in the measurement zones. The applicable conditions are governed iteratively by the limited volume details with the SIMPLE calculation. The RNG-k-epsilon model is used for storm currents because the impact of eddies on strong currents is more accurate than the standard k-epsilon model and the second booster graph method is used for the deflection of the eruptive energy and the its propagation speed. The results show that computer examination of the liquid elements of a concentric three-tube heat exchanger with inclined scales at 45 ° C provides the circulation temperature, the speed of heat movement, and, in general, a coefficient of thermal movement. more than 11.74% higher than sloped blades are at 30 ° C and 28.96% higher than straight stairs, 9mm high and 42.22% higher than three tube heat exchangers concentric fins.
