In this case the baffle helps increase the efficiency of the stove as more heat leaves the gas before it exits. The baffles prevent the rotational flow without affecting radial or longitudinal flow. The tank is provided with baffles which prevent swirling and vortex formation. Except in very large tanks, four(4) baffles are placed.
A sound attenuator, or duct silencer, sound trap, or muffler, is a noise control acoustical treatment of Heating Ventilating and Air-Conditioning (HVAC) ductwork designed to reduce transmission of noise through the ductwork, either from equipment into occupied spaces in a building, or between occupied spaces.
Sound baffles are also used in speaker cabinets to absorb energy from the pressure created by the speakers, thus reducing cabinet resonance. In 1973, Pearl P. Randolph, a school bus driver in Virginia, won a new school bus in a national contest held by Wayne Corporation for the suggestion that sound baffles be installed in the ceiling of school ...
A pair of headphones being tested inside an anechoic chamber for soundproofing. Soundproofing is any means of impeding sound propagation.There are several methods employed including increasing the distance between the source and receiver, decoupling, using noise barriers to reflect or absorb the energy of the sound waves, using damping structures such as sound baffles for absorption, or using ...
There are three types of control-type PMDs: sponge, trough, and trap. [6]: 4 Sponge PMDs are primarily used to provide the engine with propellant needed for ignition, providing the engine with propellant during a specific maneuver, and propellant control in microgravity environments. [2]: 3
A simple baffle scrubber system is shown in Figure 1. Liquid sprays capture pollutants and also remove collected particles from the baffles. Adding baffles slightly increases the pressure drop of the system. This type of technology is a part of the group of air pollution controls collectively referred to as wet scrubbers.
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
Mixing of liquids occurs frequently in process engineering. The nature of liquids to blend determines the equipment used. Single-phase blending tends to involve low-shear, high-flow mixers to cause liquid engulfment, while multi-phase mixing generally requires the use of high-shear, low-flow mixers to create droplets of one liquid in laminar, turbulent or transitional flow regimes, depending ...
