Forced Flow of Fluids across a Tube Bank

Forced Flow of Fluids across a Tube Bank 

In the case where a fluid flows across a bank of tubes, the film coefficient of heat transfer at the tube outside surface can be estimated using the following equation [1]  

In the case where fluid flows in the shell side space of a shell-and-tube-type heat exchanger, with transverse baffles, in directions that are transverse, diagonal, and partly parallel to the tubes, very approximate values of the heat transfer coefficients at the tube outside surfaces can be estimated using Equation 5.12a, if is calculated as the transverse velocity across the plane, including the shell axis [1]. 

Many correlations are available for heat transfer between liquids and the walls of stirred vessels or the surface of coiled tubes installed in the stirred vessels. For details of the different types of stirrer available, see Section 7.4.1. 

Case 1 Data on heat transfer between liquid and the vessel wall and between liquid and the surface of helical coil in the vessels stirred with flat-blade paddle stirrers were correlated as [4]
