Baffles are used to increase the fluid velocity by diverting the flow across the tube bundle to obtain higher transfer co-efficient. The distance between adjacent…

Shell is the container for the shell fluid and the tube bundle is placed inside the shell. Shell diameter should be selected in such a…

The tubes are fixed with tube sheet that form the barrier between the tube and shell fluids. The tubes can be fixed with the tube…

The number of passes is chosen to get the required tube side fluid velocity to obtain greater heat transfer co-efficient and also to reduce scale…

Tube pitch is the shortest centre to centre distance between the adjacent tubes. The tubes are generally placed in square or triangular patterns (pitch) as…

Tube OD of ¾ and 1‟‟ are very common to design a compact heat exchanger. The most efficient condition for heat transfer is to have…

Transfer of heat from one fluid to another is an important operation for most of the chemical industries. The most common application of heat transfer…

In-tube laminar flow in heat exchangers is always uneconomical, and sometimes leads to “viscosity plugging” (Sections 213 and 610). Laminar heat transfer in tubes may…

In turbulent flow, the heat transfer in the first few diameters from the inlet is higher than for fully developed flow given by Equation B-1.…

The HTRI correlation for turbulent in-tube heat transfer is: where: Nu = hi(di/12)/k = Nusselt Number (dimensionless) Re = pV(di/12)/m= Reynolds Number (dimensionless) Pr =…
