Quantitative theory of the particle-interface interaction across a nonpolar medium is developed. We consider a spherical dielectric particle (phase 1), which is immersed in a nonpolar medium (phase 2), near its boundary with a third dielectric medium (phase 3). The interaction originates from electric charges at the particle surface (e.g., the surface of a silica particle immersed in oil). The ...

The two-phase fluid model is applied in this study to calculate the steady velocity of a debris flow along a channel bed. By using the momentum equations of the solid and liquid phases in the debris flow together with an empirical formula to describe the interaction between two phases, the steady velocities of the solid and liquid phases are obtained theoretically. The comparison of those veloc...

The formation and evolution of volumetric flow structures from a rectangular orifice synthetic jet (AR=10, Re=550, Sr=0.0117, Lo=0.0855m) impinging on flat plate is investigated using phase-locked single-camera light-field particle image velocimetry (LF-PIV). An located 24 widths away the rectangle this data used to capture mechanisms involved in interaction. Flow statistics structure informati...

Two-phase flow regimes are affected by conduit position, alignment, geometry, flow direction, physical characteristics, and flow rate of each phase as well as the heat flux toward the boundaries. Due to the importance of two-phase flow, numerous regimes have been identified. The first step in studying micro-bubble formation inside a venturi tube is to recognize the type of flow regimes. In this...

An analysis on flow and heat transfer with in a two-dimensional unsteady radiative boundary layer fluid-particle interaction has been studied. The is occurred due to the suddenly linear movement of an inclined permeable stretching sheet. considered neutral medium where no external electric or magnetic field supplied. But random motion particles leads between fluid-particle, particle-particle pa...
