When hydrogen gas is used or stored within a building, as with a hydrogen-powered vehicle parked in a residential garage, any leakage of unignited H2 will mix with indoor air and may form a flammable mixture. One approach to safety engineering relies on buoyancy-driven, passive ventilation of H2 from the building through vents to the outside. To discover relationships between design variables, ...

Bare-soil evaporation involves coupled flow of liquid water, water vapor, and heat. As results in non-isothermal conditions the soil, temperature dependence transport properties thermal fluxes vapor must be accounted for. In a companion paper, we showed that Richards equation, is, single-phase model assuming isothermal conditions, is applicable to accurately determine soil hydraulic including m...

The present series of three consecutive papers develops a general theory for linear and fmite solid viscoelasticity. Because the most important object for nonlinear studies are rubber-like materials, the general approach is specified in a form convenient for solving problems important for many industries that involve rubber-like materials. General linear and nonlinear theories for non-isotherma...

Modeling and computational simulation of the carbon monoxide oxidation process, taken as a key system to analyze importance dynamic description active sites into process yield, are presented in this work. To aim, formalism transport phenomena population balances used implement realistic model that involves heat exchange, transfer mass momentum, chemical reaction, catalyst deactivation. The is s...

A sorption-enhanced process for hydrogenation of CO2 to methanol was designed and investigated by mathematical modelling techno-economic analysis. The methodology combined dynamic the cyclic reactor operation with pseudo-steady state overall process. With continuous adsorption water in process, highly pure (>99%) produced without downstream distillation. cycle optimized maximize production rate...
