It is usually difficulty to obtain filmcoefficients between the working roll and the coolant fluid as we solve the temperature field of the roll.
工作辊与冷却液之间对流换热系数的确定是轧辊温度场分析的难点。

Furthermore, the model can also be used to solve heat exchanger network problems with unequal heat transfer filmcoefficients and different construction materials.
而且此模型也可以用于求解具有不同传热膜系数和不同换热器材质的网络。

The spreading coefficients of some liquids on the paraffin and gelatin film were measured.
