I would like to obtain a design program, a free version, available to engineering students for a graduation project. The graduation project is a simple gas cycle and exhaust from it enter to HRSG . Therefore, I am looking for a program to design the HRSG , dDetermine the number and size of tubes in each part of hrsg ( evaporator, economizer, super heater ), and connect it through the program to the gas turbine. Thank you for participation.
