Flow and Heat Transfer Characteristics of Gaseous Solid Suspension Medium within Circular Riser Tubes

- 論文の詳細を見る
This paper describes an experimental study on heat transfer and flow characteristics of dilute gaseous solid suspension medium within circular riser tubes. Main attention is focused on the examination of universality and validity of correlation procedures and/or dimensionless parameters which so far have been proposed by several authors. Pressure drop and heat transfer were measured by use of the suspension of air and glass particles of three different sizes. Experimental results show that four examined procedures failed in correlating the pressure drop data of the different conditions, while they provided fairly adequate correlation for the heat transfer. Therefore, the main contribution of the suspended phase to the frictional pressure drop is seemingly through solid to solid friction between the particles and tube wall, while the change in heat transfer performance is due to the change in turbulent structure, the latter being minor for the dilute case.
