Description
Summary:In the present study, main carrier flow alterations as well as Different turbulence modulation ensued from presence of solid pellets were quantified using a Piezo-Resistive-Transducer (PRT) application. The simulation of the dilute phase characteristics was established and validated during the situation of Particle-Source-In Cell (PSI-CELL) methodology. Thus, laboratory facilities have composed and built in a superior experimental consideration. During the current study, the end goal was to achieve steady state feeding of the particulate into air stream. Experimental facilities and tests have achieved on a horizontal pipe with an inner diameter of 10 cm while the solid phase was Polyethylene particles selected to have 3.6 mm diameter. Through experimental investigations, the averaged velocity of the gas has held constant at 12 m/s and the solid particles mass loading ratios have adjusted to 0.27, 0.61, and 0.95 as well. The stochastic calculations have employed in order to track the collided particles trajectories along the horizontal pipe. As a result, the carried out outcomes show that the post-collision dynamical characteristics of the particles including angles and momentum are vital functions in the computations of solid particles trajectories. The experiments and calculations were set in a comparative with previous results acquired by the attentive researchers. However, the particles velocities have slightly augmented with increasing the loading ratio due the intensive collision rate among the pellets.
