Investigation of Flow Boiling Heat Transfer Enhancement by Using a Mesh Cylinder Insert Inside a Vertical Tube
Abstract: Based on the relationship between the flow pattern and heat transfer in an evaporative tube, a stainless steel mesh cylinder of 200 ppi with a pore diameter of 75 μm was used as the insert to regulate the flow patter and enhance the heat transfer of flow boiling in the tube. A comparative study on the evaporative heat transfer was conducted for the bare tube and the tube with the mesh cylinder insert, respectively. In the flow regimes of bubbly flow, slug flow, churn flow and churn/annular flow, the influential mechanisms of the mesh tube on the flow boiling heat transfer were disclosed. The results of this paper will provide a scientific basis for the application of flow boiling heat transfer enhancement by the mesh cylinder insert.
