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. Dynamic scraped surface heat exchanger - Wikipedia

   en.wikipedia.org/wiki/Dynamic_scraped_surface...

   An applicable technologies for indirect heat transfer use tubes (shell-and-tube exchangers) or flat surfaces (plate exchangers). Their goal is to exchange the maximum amount of heat per unit area by generating as much turbulence as possible below given pumping power limits.

5. Circulation evaporator - Wikipedia

   en.wikipedia.org/wiki/Circulation_evaporator

   Shell and tube exchangers are the most widely apparent as a result of the flexible design that can accommodate various pressure and temperature values. [1] Forced circulation exchangers can employ either horizontal or vertical shell and tube heat exchangers, allowing the exchange of heat between fluids within and outside the tubes (that exist ...

6. Ground-coupled heat exchanger - Wikipedia

   en.wikipedia.org/wiki/Ground-coupled_heat_exchanger

   Ground-coupled heat exchanger may also use water or antifreeze as a heat transfer fluid, often in conjunction with a geothermal heat pump. See, for example downhole heat exchangers. The rest of this article deals primarily with earth-air heat exchangers or earth tubes.

7. Waste heat recovery unit - Wikipedia

   en.wikipedia.org/wiki/Waste_heat_recovery_unit

   Economizer: In case of process boilers, waste heat in the exhaust gas is passed along a recuperator that carries the inlet fluid for the boiler and thus decreases thermal energy intake of the inlet fluid. Heat pumps: Using an organic fluid that boils at a low temperature means that energy could be regenerated from waste fluids. Run around coil ...

8. Coiled tubing - Wikipedia

   en.wikipedia.org/wiki/Coiled_tubing

   In the oil and gas industry, coiled tubing refers to a long metal pipe, normally 1 to 3.25 in (25 to 83 mm) in diameter which is supplied spooled on a large reel. It is used for interventions in oil and gas wells and sometimes as production tubing in depleted gas wells. Coiled tubing is often used to carry out operations similar to wirelining ...
