| Abstract: |
| Thermal radiation is one of the basic forms of heat transfer between particles.Computing efficiency and accuracy are the difficulties to calculate the view factors when simulating thermal radiation.In this paper,the Fibonacci number is used to discretize the surface of non-equal-diameter particles,and the view factors are calculated based on it.Subsequently,the non-uniform transformation in the Z direction is adopted to improve computational accuracy.It is indicated that a relative error of 5% for the view factor in a packed bed containing different numbers of spheres calculated is obtained by the proposed method.Compared with the traditional Monte Carlo method,the computational efficiency is improved by about 30%. |
