Design of Bulk-Solids Moving-Bed Heat Exchangers

Presented here are equations governing heat transfer in a moving-bed heat exchanger, along with a numerical method for solving them Moving-bed heat exchangers (MBHE) represent an efficient method for heating or cooling bulk-solid materials compared to other technologies, such as…

A sandwich catalyst boosts H2 production

Platinum has been the main catalyst for hydrogen-producing reactions, but it has a low affinity for water molecules. This results in a slow rate of water electrolysis. Attempts have been made to combine metal-sulfide with platinum nanoparticles that promote water…

Thermodynamics of Gas Piping Systems

Understanding the implications of adiabatic and isothermal flow assumptions is necessary to have confidence in when to use such assumptions Every engineer uses assumptions because every analysis has an overabundance of variables to consider. Often, there are just too many…
