Numerical Calculations and Cold Tests for Flow Fields of a 220t/h Retrofitted Oil-Boiler

摘要

In this paper, cold simulation experiments and numerical calculations are conducted to predict 3-D flow field aerodynamics for an oil furnace after being retrofitted due to its fuel variation. K-ε model and SIMPLE program under body-fit-coordination (BFC) system, in which TTM non-orthogonal method is used to control the irregular geometric boundary, are adopted to solve the control equations. Model tests are conducted to check the calculation results, showing that they are in agreement with each other.
