3D Numerical Calculation of Heat Transfer and Structure Improvement on Tube Adsorbent Bed
摘要
Abstract
To study the influence of diameter and number of the heat transfer tube on the heat transfer , the parameters of the adsorbent bed were calculated when the diameter and number of the heat transfer tube were changed in the same heat transfer area or the same volume of the adsorbent bed.A three-dimensional structure model of the adsorbent bed is established.Temperature field is numerically investigated by using FLUENT.It is shown from results that the temperature of the radial direction and axial direction section goes up quickly with the increasing of the number of the heat transfer tube when the heat transfer area of adsorbent bed or filling volume is certain.The temperature distribution in the bed is more uniform with the increasing at the number of heat transfer tube.Moreover, the flow mass flow has not much impact on the bed temperature.By analyzing the results of simulation, the initial structure of the adsorbent bed is improved.As a result, the volume of the adsorbent the bed is not changed much, but the area of heat transfer in the new adsorbent bed increases considerably from 0.58 m2 to 1.11 m2.At the same time, the heat transfer is strengthened and the cycle time is shorted.关键词
