Binary Brayton cycle with two isothermal processes

•This paper presents binary Brayton cycle with two isothermal processes.•Different parameters affecting the cycle performance have been studied.•The present cycle is a promising cycle for future power generation.

The literature introduced isothermal concept and binary Brayton cycle as two promising methods used to enhance the performance of the gas turbine. Consequently, this work presents a cycle based on the blending of the two methods. This cycle is composed of gas turbine topping cycle with isothermal combustion and air turbine bottoming cycle with isothermal heating. Different parameters affecting the cycle performance have been studied. Simulations demonstrate that the present cycle achieves drastic enhancement in performance. The cycle merits justify its potential utilization for future power generation.
