furnace cavity meaning in English

炉膛

2 . in order to meet the real - time simulation and guarantee specified ratio of precision , this paper had simplified and supposed some thermal process in module and use the lumped parameter way to model . for some special components , such as furnace cavity or water screen , had been reached good ratio of precision of simulation by divided into three parts ( upper area , intermediate area and lower area ) to model separately because of the huge difference of heat loading in vertical direction
2 、为满足实时仿真的要求而同时要保证有一定仿真精度,本文对模型做出了一定的假设和简化,并且主要采用集总参数法进行建模,对于一些特殊部件,比如炉膛和水冷壁,由于其竖直方向热负荷差异较大,本文将其分为上、中、下三个区域,分别采用集总参数建模,达到比较好的仿真精度。
