The literature introduced binary Brayton cycle and the isothermal concept 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.

Vast researches have been performed to enhance the torque converter due to its significance in different power transmission applications. However, some of its problems are not completely solved. Consequently, this work introduces a principal modification to the torque converter not only to eliminate such problems but also to operate it with advanced features. The present torque converter operates with the power splitting concept where its input power is split into two power paths, then combined after regulation. This system is represented by a conventional torque converter attached to one planetary gear set. Two unique positive displacement hydraulic couplings of the same type are utilized to regulate power in the two power paths. A feasible model is derived to predict and study the conventional torque converter performance where the global intrinsic losses are empirically included. Based on this model and gear kinematics, the simulated results demonstrate that the present torque converter operates as a continuously variable transmission used for different applications.
