Temperature distribution in a thermal bridge This thermal image shows a thermal bridging of a high-rise building (Aqua in Chicago). A thermal bridge, also called a cold bridge, heat bridge, or thermal bypass, is an area or component of an object which has higher thermal conductivity than the surrounding materials, [1] creating a path of least resistance for heat transfer.

A regenerative thermal oxidizer (RTO) is an example of a waste heat recovery unit that utilizes a regenerative process. A waste heat recovery unit ( WHRU ) is an energy recovery heat exchanger that transfers heat from process outputs at high temperature to another part of the process for some purpose, usually increased efficiency.
Base isolators for seismic isolation of buildings, bridges, etc. Base isolators made of layers of neoprene and steel with a low horizontal stiffness are used to lower the natural frequency of the building. Some other base isolators are designed to slide, preventing the transfer of energy from the ground to the building. Tuned mass dampers
The calculation of the heat loss due to linear thermal bridging is relatively simple, given by the formula below: [3] H T B = y ∑ A e x p {\displaystyle H_{TB}=y\sum A_{exp}} In the formula, y = 0.08 {\displaystyle y=0.08} if Accredited Construction details used, and y = 0.15 {\displaystyle y=0.15} otherwise, and ∑ A e x p {\displaystyle ...
The heat conduction can be minimized by any of the following: reducing the cross sectional area of the bridges, increasing the bridge length, or decreasing the number of thermal bridges. One method of reducing thermal bridge effects is the installation of an insulation board (e.g. foam board EPS XPS, wood fibre board, etc.) over the exterior ...
Vehicle emissions control is the study of reducing the emissions produced by motor vehicles, especially internal combustion engines.The primary emissions studied include hydrocarbons, volatile organic compounds, carbon monoxide, carbon dioxide, nitrogen oxides, particulate matter, and sulfur oxides.
The thermal protection system for the underside of the vehicle, comprising the nose, leading edges and lower surface of the wing, were designed and made by Herakles [32] using a ceramic matrix composite (CMC), carbon/silicon-carbide (C/SiC), in this case based on the liquid silicon infilration (LSI) process (see manufacturing procedures above ...
Fluid–structure interactions are a crucial consideration in the design of many engineering systems, e.g. automobile, aircraft, spacecraft, engines and bridges. Failing to consider the effects of oscillatory interactions can be catastrophic, especially in structures comprising materials susceptible to fatigue.
