Study of MHD with Couple Stress Fluid on Squeeze-Film Characteristics of Curved Annular Circular Plates
摘要
The consequences of couple stress fluid and applied magnetic field on the squeeze-film attributes between the curved annular circular plates are analyzed. Solving the governing equations, the non-dimensional expressions for film pressure, load-carrying capacity, and squeezing time are obtained, and results are discussed by plotting graphically for various parameters like Hartmann number, couple stress parameter, and curvature parameter. It is observed that the transverse magnetic field and couple stress fluid increase the load capacity, time of squeeze film and pressure. Also, it was noted that an increase in upper plate curvature increases the pressure, whereas increases in lower plate curvature decrease the loading-capacity and time of squeeze film.
