EXPERIMENT TOPICS 

• To demonstrate indirect heating or cooling by transfer of heat from one fluid stream to another when separated by a solid wall (fluid to fluid heat transfer) 

• To perform an energy balance across a concentric tube heat exchanger and calculate the overall efficiency at different fluid flow rates. 

• To demonstrate the differences between countercurrent flow (flows in opposing directions) and cocurrent flows (flows in the same direction) and the effect on heat transferred, temperature efficiencies and temperature profiles through a concentric tube heat exchanger. 

• To To determine the overall heat transfer coefficient for a concentric tube heat exchanger using the logarithmic mean temperature difference to perform the calculations (for counter-current and co-current flows). 

• To investigate the effect of changes in hot fluid and cold fluid flow rate on the temperature efficiencies and overall heat transfer coefficient 

• To investigate the effect of driving force (difference between hot stream and cold stream temperature) with counter-current and co-current flow.

Datasheet


GOTT-HEXT-05 is an optional item that work with Heat Exchanger base unit. The Extended Concentric Tube heat exchanger is mounted on the base unit. The Extended Concentric tube heat exchanger is very similar to the GOTT-HEXT-CT Concentric Tube Heat Exchanger except consists of Two pairs of concentric tubes are arranged in series in a double U format to reduce the overall length and to provide three mid position measuring points. ln normal operation, hot water passes through the 'HOT OUT' braided hose and self-sealing coupling into the inner stainless tube. It then flows through the heat exchanger and leaves. Cold water flows from the 'COLD OUT' hose through the annulus between the clear plastic tube and the inner stainless tube. With the hot water in the inner tube, losses from the system to the outside are minimized while still allowing students to see the construction of the unit. As the cold stream warms above the ambient temperature however there will be some external losses. The midway points of both hot and cold streams are fitted with thermocouples to measure the stream temperatures. Miniature thermocouple plugs take these signals to the temperature indicator.
