The different parameters that affect the gas-solidmixture flows metering process were determined and analyzed. In order to conductthe study, an experimental set-up was designed and manufactured in the laboratoryof the thermal power engineering in Menoufia University. Furthermore, sevennonstandard (long-throated) geometrical Venturi models with different diametersratios and throat lengths were selected guided by previous literature andmanufactured to be used in the present experimental work. Additionally, theexperimental study was performed on the selected models to determine the effect ofdifferent Venturi meter geometric models on pressure drop sensitivity, pressurerecovery, and to seek a viable method for determining loading ratio for suspendedgas-solid flows in the Venturi. The results showed that the coal loading ratio affectedgreatly and positively both the pressure drop and recovery ratios of air-coal mixtureflows in the Venturi. However, inlet and exit geometries of the Venturi had smallereffect on the pressure drop and recovery ratios than the coal loading ratio andparticles diameter range. Additionally, decreasing the diameters ratio and increasingthe throat length improved the Venturi pressure drop sensitivity to solids loading.Finally, the experimental results helped greatly to analyze the different parametersconcerning the air-coal mixture flows in a Venturi meter and provided an insight onthe feasibility of using the Venturi as a metering tool for suspended gas-solid mixtureflows in a future continuation of the present work.}, keywords = {Experimental study,Pressure drop and recovery,Venturi meter,Gas-solid mixture flows,and Loading ratio}, url = {https://amme.journals.ekb.eg/article_34977.html}, eprint = {https://amme.journals.ekb.eg/article_34977_991102bcf9ae4350cf88fcf8f176f2fa.pdf} }
