A Pushrod is acting as a slender beam under axial loading and has a variety of applications, like in the automobile industry. For study purposes, a pushrod has been considered which is made of a superelastic shape memory alloy of a circular cross-section. The behavior of the pushrod is scrutinized during the applied force of vibration acting uniformly and eccentrically upon it. These dynamic loadings render a significant impact on its elastic behavior and a constructive formula for the deflection of the beam from its neutral axis is introduced. With this equation, the elastic curve deviations from its initial position are analyzed and its response to the increase in the number of modes is evaluated. The deflection of the beam is highest when the mode number is 1 and with the raise of modal shapes, the deflection tends to get decreased. A comparison with the static beam under affiliated force depicts that the deflection escalates in the beam under dynamic loading. With the change of force functions, different deflection curves have been calculated and from their comparison, the characteristics of this slender pushrod have divulged its other features too. For engineering structure study and design, vibration analysis has been marked as a must-to-do list. [ABSTRACT FROM AUTHOR]

A numerical investigation is performed in the turbulent combined-convection boundary layer with aiding flows in air along a heated vertical flat plate at a higher freestream velocity (Reδ0 = 600) by time-developing direct numerical simulation (DNS). At higher freestream velocity, the transition from laminar to turbulent delays for aiding flows and relatively a lower and higher heat transfer rates are observed, respectively, in the laminar and turbulent region compared to that of lower freestream velocity. The wall shear stresses are higher in the laminar region compared to that in the turbulent region, and at higher freestream velocity, the wall shear stress in the transition region shows a higher peak value. The intensity of velocity and temperature fluctuations for aiding flows with higher freestream velocity become appreciably lower than that for lower freestream velocity due to the laminarization of the boundary layer.
