Results show that massarearatio (mar) is a primary factor to average daily efficiency and instantaneous efficiency curve of tubular solar water heaters is not straight line.
结果表明，水量配比(MAR)是影响日平均效率的主要因素；真空管式太阳热水器的瞬时效率不是线性分布。

In the model the exit arearatio, solid particle mass ratio, fuel enthalpy of combustion, jet gas molecular weight, chamber stagnation temperature, flight Math number etc. have been considered.
The analysis includes the concentration ratio at the base of a GCL, advective and diffusive mass flux, and total accumulated contaminant mass through the liner per unit area.
