- Abstract:
- The cooling proeess of unsteady temperalure field in the erew eapsule is simulated, making use oleomputational fluid dynamies software FLUEN’T and the algorihm of PBCS, in addition to RNGk - s two equa.tion model replaeed with the three-dimensional turbulenee model. And then the workflow is established, whichineludes numerieal simulation, approximate model and oplimization algorihm, "The numerieal simulation trainsapproximation model, using radial basis funetion ( RBF) neural network approximation model instead of thehigh eost of the simulation ealeulation. Multi-island GA is chosen to optimize the wind direetion. The wind direetion oplimized and the wind direelion vertieal surace of inlet tuyere are ealeulated by simulation software respeelively. Compared before and afler the optimization of heat flow value and temperature contours, front sealheat llow inereases by 11.98%6 after oplimization, rear seat heat flow inereases by 17.81% afler oplimizalionand the oplimized cooling area and cooling degree are improved.
