관수된 충전칼럼에서의 압력손실 = Pressure drop in irrigated packed columns

다국어 초록 (Multilingual Abstract)

In this work, an equation for determining the pressure drop of irrigated packings is introduced. This is built up from the well-known channel model. It is valid for the whole load range up to the flooding point. To apply the pressure drop formula, it is necessary to know the operating conditions, the liquid hold-up and the from factor μ specific to the packing element or group of packings. The method of calculating the pressure drop is illustrated by means of an example
1) The agreement obtained between the calculations and the experiments is regarded as good. As expected, the measurements below the loading line are reproduced more exactly-the average error ￣δ₁(△P/H) in Table l(a)-(c) is considerably less than 10%. The measurements above the loading limit including the pressure drop at the flooding point are reproduced with an average relative error ￣δ₂(△P/H) of about 15%.
2) Another advantage of the method chosen here the represent the pressure drop is that, by means of a packings element constant μ characteristic of almost every family of packing elements or group of packing elements of similar construction, it is easy to compare the pressure drop of the particular type of packing element and its height with other packing elements. The advantage of this model is that know-ledge of the dry pressure drop of the packing is not necessary.
To reinforce the above dependences a numerical example is added with the help of which the determination of the pressure drop is demonstrated.
