2. Heat transfer enhancement - Wikipedia

   en.wikipedia.org/wiki/Heat_transfer_enhancement

   Helically coiled tube with secondary flow. The coil spring insert may enhance heat transfer without turbulence or additional heat transfer surface area. A secondary flow is induces the fluid creating two longitudinal vortices. This could result, (in contrast to a right tube) in highly non-uniform local around the periphery of the tube.

3. Shell-and-tube heat exchanger - Wikipedia

   en.wikipedia.org/wiki/Shell-and-tube_heat_exchanger

   In shell-and-tube heat exchangers there is a potential for a tube to rupture and for high pressure (HP) fluid to enter and over-pressurise the low pressure (LP) side of the heat exchanger. [8] The usual configuration of exchangers is for the HP fluid to be in the tubes and for LP water, cooling or heating media to be on the shell side.

4. Tubular Exchanger Manufacturers Association - Wikipedia

   en.wikipedia.org/wiki/Tubular_Exchanger...

   The member companies of TEMA must demonstrate high quality exchanger fabrication standards, and possess in-house engineering capability for mechanical and thermal design of shell and tube type heat exchangers. Companies may fabricate other equipment in addition to heat exchangers. The current member companies of TEMA (in alphabetical order) are:

5. NTU method - Wikipedia

   en.wikipedia.org/wiki/NTU_Method

   The number of transfer units (NTU) method is used to calculate the rate of heat transfer in heat exchangers (especially parallel flow, counter current, and cross-flow exchangers) when there is insufficient information to calculate the log mean temperature difference (LMTD). Alternatively, this method is useful for determining the expected heat ...

6. Baffle (heat transfer) - Wikipedia

   en.wikipedia.org/wiki/Baffle_(heat_transfer)

   It is used in some household stoves [1] and in some industrial process vessels (tanks), such as shell and tube heat exchangers, chemical reactors, and static mixers. Baffles are an integral part of the shell and tube heat exchanger design. A baffle is designed to support tube bundles and direct the flow of fluids for maximum

7. Enhanced heat transfer - Wikipedia

   en.wikipedia.org/wiki/Enhanced_heat_transfer

   Size Reduction: If the heat exchange rate (Q) is held constant the heat exchanger length may be reduced. This will provide a smaller heat exchanger. Increased heat exchange rate: This may be exploited either of two ways: Reduced driving temperature difference (ΔTm): If Q and the total tube length (L) are held constant, the ΔTm may be reduced.
