Their occurrence is caused by south-easterly air flow that blows hot air from mainland Europe, combined with strong summer sunshine.
This study presents the effects of precipitation pH, solid content, slurry feed rate, atomization pressure, hot air temperature and hot air flow rate on the particle size distribution of SD-HA.
Consisting of a quartzite-rock bed that is charged with a hot air flow and discharged by cold air counter-flow, the storage essentially operates like a regenerator.
At peak periods, timber stack in the drying chamber receives hot air flow from the collector and the transparent roof simultaneously.
The retainer allows keeping the air gate valves fully opened and prevents their uncontrolled closure under the action of a rapidly ascending hot air flow inside the PHRS shell.
The configuration without break edge provides more efficient air film compared to the others; thus it provides enhancement on the heat transfer between hot air flow and the cold surface.
One of the main tasks during the design or simulation and analyses of the utility steam boiler operation is the prediction of a distribution of mill gases and hot air flow rates between burners' sections.
A one-dimensional unsteady state mathematical model of coupled heat and mass transfer equations is accomplished to simulate the convective drying of cylindrical quince slices with axis parallel to the hot air flow.
At Mach 4 or 5, the air flow would become dangerously hot but this heat exchanger - consisting of a dense and closely-guarded bundle of tiny tubes - would chill things down to a manageable temperature in milliseconds.
Ethanol was evaporated with the help of a steady hot air flow (100 °C, ∼20 min).
