Mathematical modeling of gas flow including heat transfer in spiral heat exchanger
Original language description
The paper presents the numerical solution of gas flow in a spiral heat exchanger, which flowing water is heated. Gaseous combustion products are derived from the combustion of natural gas in micro-turbine, which reaches tens of power [kW]. The paper defines a mathematical model of gas flow in the exchanger, including consideration of heat transfer through the conductive spiral heat exchanger. Conductive heat exchanger areas are different wall and the insulation layer that surrounds the heat exchanger itself. Inlet boundary conditions for gas and water were got from the experimental measurements. Then defined mathematical model was solved numerically in programming software ANSYS Fluent13. The results of numerical simulations are presented in the basicdistribution of current values in the individual sections of exchanger. Subsequently, variables are evaluated to determine the energy analysis of the heat exchanger.
