A typical reinery or chemical plant can emit 600­ 700 tons per year of VOCs from leaking equipment, such as valves, connectors, pumps, sampling con­ nections, compressors, pressure-relief devices, and open-ended lines. Table 3.1 shows the primary sources of emissions from components subject to equipment leak regu­ lations.

Bio-particulate matter includes grains, cereal crops, and biomass that are considered discrete materials with irregular size and shape. Although the flow of these particles can behave like a continuum fluid at times, their discontinuous behavior cannot be simulated with traditional continuum-based modeling. The Discrete Element Method (DEM), coupled with Computational …

Fuel cells are electrochemical energy devices that directly convert chemical energy into electric power without combustion, where the fuels (e.g. H 2) are oxidized in the anode to generate electrons and H + or H 2 O in acidic and alkaline electrolytes, respectively, as shown in Fig. 1(a). Then the electrons flow to the cathode reducing O 2 into H 2 O or OH −.

Phase change materials (PCMs) used for the storage of thermal energy as sensible and latent heat are an important class of modern materials which substantially contribute to the efficient use and conservation of waste heat and solar energy. The storage of latent heat provides a greater density of energy storage with a smaller temperature ...

HT-7 ∂ ∂−() −= f TT kA L 2 AB TA TB 0. (2.5) In equation (2.5), k is a proportionality factor that is a function of the material and the temperature, A is the cross-sectional area and L is the length of the bar. In the limit for any temperature difference ∆T across a length ∆x as both L, T A - T B → 0, we can say dx dT kA L T T kA
