- Cylinders are essential in constructing several engineering designs where fluid passes over them. Under varying environmental conditions, the fluid flows with impulse, affecting design structures considerably. This paper presents the numerical analysis of incompressible low-Re gusty flow with impulse inlet passing through three staggered cylinders. The problem is numerically simulated and investigated for two distinct variable factors keeping one constant at a time: inlet gust frequency and Reynolds number. The vorticity contours are obtained that provide information about local rotation. The streamlines are obtained to identify the wake region. The C L , C D, and St are computed. The results show a beneficial effect of variability in impulse intake velocity on the wake region generated between and behind the cylinders. It represents enhanced flow characteristics derived from low angular gust frequency value of intake velocity fluctuation.

The characteristics of flow over a square cylinder in the vicinity of a plane stationary wall have been numerically investigated. 2D time-dependent incompressible flow at low-Reynolds numbers of 100 and 200 has been calculated using the finite volume method. CFRUNS scheme is used for pressure-velocity coupling in numerical calculation. The authors have tried to make an attempt to analyze the features of the complex flow field through flow streamlines and the vorticity contours. The impact of the gap between the cylinder and the plane wall upon flow pattern behavior is also studied. An intense interaction between vorticity in the boundary layer generated over the plane wall and the vorticity associated with the shear layer emanating from the separation points on the cylinder surface has been observed producing a very complex flow field in the cylinder wake and the gap between the cylinder and the wall.

In this research paper, the shape optimization of the NACA 4412 airfoil has been carried out at 00 angle of attack and stall angle of attack, at moderate Reynolds number. The NACA 4412 airfoil has been used in sports planes which have a higher cruise speed compared to cargo planes. Hence, the shape of the airfoil needs to be optimized for achieving a higher lift to drag ratio. The adjoint method has been used to optimize the shape using ANSYS Fluent software.

The main aim of this work is to performnumerical analysis of heat transfer in heatsinks using fins of different shapes. Ansys FLUENT has been used for the present simulation. Authors have used rectangular and conic shaped fins arranged in staggered fashion for the analysis. The effect of aerodynamic shaping of fins on thermal behavior of staggered plate heatsinks were analyzed in the present study. The present results were validated with the numerical and experimental results found in open literature. The comparison of staggered rectangular and conic fins were performed by considering quality factor, pumping power and heat transfer rate experienced by the respective fins. It has been observed that aerodynamically shaped fins have better overallperformance in terms of quality factor and pumping power.
