Platinum group metals, such as Pd and Pt, found in three-way catalyst converters were recycled in a two-step method: hydrodynamic cavitation followed by sonoelectrochemical dissolution. High shear forces were obtained by using a convergent nozzle wit

Regularizing the operation of unglazed transpired collectors by incorporating phase change materials
Publikováno v:
Energy Conversion and Management. 184:681-708
A new type of unglazed transpired collector (UTC) incorporating phase change materials (PCMs) is presented. A time-dependent model consisting of eight 1D PDEs is derived from basic principles. Mass, momentum and energy balance equations for air flow
