# Baffles Thermal Design Considerations

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 Thermal Design Considerations

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…

# Tube Sheet Thermal Design Considerations

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…

# Tube Passes Thermal Design Considerations

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, Tube-layout and Tube-count Thermal Design Considerations

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 Thermal Design Considerations

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…

# Classification of Heat Exchangers

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 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…

# Turbulent Entry Region Effects

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.…

# In-Tube Turbulent Heat Transfer

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 =…
