  7. Abstract:
  8. Today, due to increasing electricity consumption and demand, the use of conventional systems such as thermal, hydro and nuclear power plants is not enough to convert energy. Over the past century, scientists have sought to discover new technologies for exploiting different forms of energy and converting them into high-efficiency electrical energy. One of these ways is to use the phenomenon of magnetohydrodynamics (magnetic fluid dynamics) to convert thermal energy directly into electrical energy. Magnetohydrodynamics is a theoretical field that studies the dynamics of fluids with electrical conductivity. Induction magneto-hydrodynamic generators use ionized hot plasma (a quasi-neutral gas of charged and neutral particles that exhibits a collective behavior) to generate electrical energy in a simpler cycle than existing power plants. In these generators, the plasma is ionized in a process and under the influence of an external electric field, produces an electric current and then this current is magnetically coupled with the external winding and generates electricity in that winding. The only difference between induction and rotary magnetohydrodynamic generators is the use of plasma instead of moving parts. In this research, the structure of this type of energy conversion and its surrounding requirements, including various types of magnetohydrodynamic generators in terms of structure, cycle type and finally to simulate induction MHD generator and also provide an optimal design of these generators to increase efficiency for gas turbine power plants. Finally, the results of the MHD generator in the initial and optimal state are compared with each other, which has increased the output power from 18114 to 19260 watts. It should be noted that in this research, simulation and optimization using Kamsol software version 5.5 has been used to analyze the performance of the generator by finite element method
