The Shell & Tube Heat Exchanger Apparatus is designed to study heat transfer between two fluids separated by a series of tubes enclosed in a shell. This equipment demonstrates the thermal performance of one of the most widely used industrial heat exchangers in power plants, refineries, and chemical processing.

Educational Objectives

• Understand the working of a shell & tube heat exchanger.

• Study heat transfer in parallel flow and counterflow modes.

• Determine overall heat transfer coefficients.

• Calculate log mean temperature difference (LMTD).

• Evaluate exchanger performance under different flow rates.

Performance Measurement

• Inlet and outlet temperatures of hot and cold fluids.

• Measurement of flow rates.

• Calculation of heat transfer rate and LMTD.

• Comparison of experimental and theoretical efficiency.

Panel and Instruments

• Shell & tube heat exchanger unit (1-1 pass or 1-2 pass design).

• Hot and cold water circulation with storage tanks.

• Pumps for controlled fluid circulation.

• Thermocouples with digital display.

• Flow meters for both hot and cold fluids.

• Control valves for adjusting flow configuration.

• Safety guard and emergency stop.
