  • Predicting acoustic transmission loss through laminated glass with air and porous layers

    This study analyses the sound transmission characteristic of various laminated glass designs with application to motor vehicles. The porous interlayer in the laminated glass is filled with polyvinyl butyral (PVB) that serves as an acoustic damper. To model the physics behind the sound transmission losses of the fluid, solid and porous layers, acoustic noise transfer matrices are used to relate ...

  • Investigation into noise problems in vehicle structure using vibro-acoustic approach

    The main focus of this paper is the study of the relationship between components of vibration and noise inside the passenger cabin of a production vehicle. The noise inside automobiles is largely composed of contributions from the engine, ground and wind. The engine and tyres successively transfer the vibration via the structural connections to the body panels, which then propagates through the ...

  • Treatment of Water-Wash Paintbooth Effluents in the Automotive Industry

    During the coating process of car bodies in water-wash spray booth, around 40% of the sprayed paint does not reach the support; these paint particles sprayed into the air are called “overspray”. By using a dawn-draft positive air pressure coming from the ceiling of the cabin, the polluted air is forced vertically downward toward a grating on the floor under which a constant stream of water is ...

  • Combination filters

    Simply defined, a combination filter is one that does at least one other processing job at the same time as filtering a suspension. The classic example, of course, is the packed bed of activated charcoal, which acts as a remover of chemical impurities from the suspension, as well as removing dust particles - although this is actually not a very good example, because it is primarily an adsorber, ...

  • From 370km above the earth to 11000m under the sea

    It’s a bold strapline – but what does it mean? Have we opened an atmosphere research facility in outer space? Organised an aquatic Charity Day in the Mariana Trench? Well, if you didn’t know anything about Analox you’d be forgiven for wondering. After all, three-hundred and seventy kilometres above the earth is a long way from Stokesley. And eleven thousand metres under ...

  • All That You Need to Know About Metal Fabricated Pressure Vessels

    Think of the balloon that sometimes bursts out with a noise while being blown at. We at once know that it bursts out as it fails to withstand the excess pressure. However, for obvious reasons we cannot expect the same out of metal fabricated pressure vessels that are used for numerous industrial applications in factories, plants and manufacturing sites. There are several factors that need to be ...
