GPU-based parallel method of temperature field analysis in a floor heater with a controller
A parallel method enabling acceleration of the numerical analysis of the transient temperature field in an air floor heating system is presented in this paper. An initial-boundary value problem of the heater regulated by an on/off controller is formulated. The analogue model is discretized using the...

| description | A parallel method enabling acceleration of the
numerical analysis of the transient temperature field in
an air floor heating system is presented in this paper. An
initial-boundary value problem of the heater regulated by
an on/off controller is formulated. The analogue model is
discretized using the implicit finite difference method. The
BiCGStab method is used to compute the obtained system
of equations. A computer program implementing simultaneous
computations on CPUand GPU(GPGPUtechnology)
was developed. CUDA environment and linear algebra libraries
(CUBLAS and CUSPARSE) are used by this program.
The time of computations was reduced eight times
in comparison with a program executed on the CPU only.
Results of computations are presented in the form of time
profiles and temperature field distributions. An influence
of a model of the heat transfer coefficient on the simulation
of the system operation was examined. The physical
interpretation of obtained results is also presented.Results
of computations were verified by comparing them with solutions
obtained with the use of a commercial program -
COMSOL Mutiphysics. |
