As mentioned, baffles deal with the concern of support and fluid direction in heat exchangers. In this way it is vital that they are spaced correctly at installation. The minimum baffle spacing is the greater of 50.8 mm or one fifth of the inner shell diameter. The maximum baffle spacing is dependent on material and size of tubes.
A slosh baffle is a device used to dampen the adverse effects of liquid slosh in a tank. Slosh baffles have been implemented in a variety of applications including tanker trucks , and liquid rockets , although any moving tank containing liquid may employ them.
Baffle (liquid mixing), auxiliary devices employed in tank which suppress the effects of slosh dynamics; Baffle (heat transfer), a flow-directing or obstructing vane or panel used in some industrial process vessels (tanks) Baffle (medicine), a tunnel or wall surgically constructed within the heart or primary blood vessels to redirect blood flow
A system of valves or baffles, or both, is usually incorporated to simultaneously operate a small radiator inside the vehicle. This small radiator, and the associated blower fan, is called the heater core, and serves to warm the cabin interior. Like the radiator, the heater core acts by removing heat from the engine.
In fluid dynamics, slosh refers to the movement of liquid inside another object (which is, typically, also undergoing motion). Strictly speaking, the liquid must have a free surface to constitute a slosh dynamics problem, where the dynamics of the liquid can interact with the container to alter the system dynamics significantly.

Selective catalytic reduction (SCR) injects a reductant such as ammonia or urea — the latter aqueous, where it is known as diesel exhaust fluid (DEF) — into the exhaust of a diesel engine to convert nitrogen oxides (NO x) into gaseous nitrogen and water.
Diesel exhaust fluid (DEF; also known as AUS 32 and sometimes marketed as AdBlue [3]) is a liquid used to reduce the amount of air pollution created by a diesel engine. Specifically, DEF is an aqueous urea solution made with 32.5% urea and 67.5% deionized water .
Non-ideal hydraulic behavior is commonly classified by either dead space or short-circuiting. These phenomena occur when some fluid spends less time in the reactor than the theoretical residence time, . The presence of corners or baffles in a reactor often results in some dead space where the fluid is poorly mixed. [6]
