The averaged gas velocity of flowing backward between the exhausting duct and the mixture tube increases with the rise of the main nozzle flux and the downwash flow velocity.
The perimeter averaged heat transfer coefficients depend on heat flux, mass flow rate, quality and saturated pressure.
截面平均换热系数则与质量流速、热流密度、质量干度和蒸发压力密切相关。

Thus the averaged relationships between the flux density of the direct solar radiation and the air mass under various coefficients of transparency P2 were obtained.
