The influence of gas‒solid injector structural parameters(9-12) on injection performance

A gas‒solid injector acts as a power source in a pneumatic conveying system, and its structural parameters have a great influence on the injection and conveying performance of the system. This study uses a pure flow field experiment bed, a particle pneumatic injection experiment bed, and CFD‒DEM coupling simulation technology, as well as a gas‒solid injection experiment and gas‒solid coupling simulation datasets of gas‒solid injectors under four different particle mass flow rates, to present a pure flow field injection experiment and pure flow field simulation datasets of gas‒solid injectors with different structural parameters in the absence of particles. We evaluate the injection performance of gas‒solid injectors through the injection ratio, average pressure, transport time, conveying ratio, energy increasing ratio, and total energy consumption ratio. This dataset has great value for engineers and designers, providing a reference for designing gas‒solid injectors and other pneumatic conveying devices.
