Coexistence of natural and forced vortex dislocations in step cylinder flow
(Journal article; Peer reviewed, 2023) -
Diameter ratio effects in the wake flow of single step cylinders
(Peer reviewed; Journal article, 2020)Vortex interactions behind step cylinders with diameter ratio 2 ≤ D/d ≤ 3 at Reynolds number (ReD) 150 were investigated by directly solving the three-dimensional Navier–Stokes equations. In accordance with the previous ... -
Different topologies of natural vortex dislocations in Mode A wake
(Journal article; Peer reviewed, 2022) -
Effect of the angle of attack on flow around an elliptic cylinder near a moving wall
(Journal article; Peer reviewed, 2022)The present work investigates the combined effect of the angle of attack (AOA) (the angle between the semi-major axis of the cylinder and the vertical axis), and the gap ratio G/D (where G represents the distance between ... -
Flow over a single shallow dimple
(Peer reviewed; Journal article, 2024) -
Hydroplastic response of a square plate due to impact on calm water
(Peer reviewed; Journal article, 2020)This paper investigates large, plastic deflections of a square plate due to impact on calm water. Most research in the area has examined linear elastic structural responses to such impact, but hydrodynamic responses during ... -
Near-wall effect on flow around an elliptic cylinder translating above a plane wall
(Peer reviewed; Journal article, 2020)In this work, the flow over an elliptic cylinder near a moving wall is investigated for Reynolds numbers less than 150. Here, the ratio between the gap (i.e., the distance between the cylinder and the wall) and the length ... -
A numerical study of separation and stagnation points for steady and unsteady flow over an elliptic cylinder near a moving wall
(Peer reviewed; Journal article, 2021)Flow separation around an elliptic cylinder with an aspect ratio of 0.4 near a moving wall is investigated numerically for Re 2 ½5; 150 with G=D 2 ½0:1; 2 (where G denotes the distance between the cylinder bottom and the ... -
Scaling laws for the water entry of a three-dimensional body
(Peer reviewed; Journal article, 2021)The present experimental investigation is a new way of conducting tests on model scale and of interpreting the results for the water entry of a free-falling conical body shape entrapping an air cavity. A three-dimensional ... -
Three-dimensional wake transition behind an elliptic cylinder near a moving wall
(Peer reviewed; Journal article, 2021)In this work, the flow over an elliptic cylinder near a moving wall is investigated for Reynolds numbers less than 150. Here, the ratio between the gap (i.e., the distance between the cylinder and the wall) and the length ... -
Unsteady hydrodynamic forces of solid objects vertically entering the water surface
(Journal article; Peer reviewed, 2019)We investigate the unsteady hydrodynamic force of solid objects vertically entering water with an air cavity behind the falling body. Physical models are proposed to represent the force components corresponding to the body ... -
Validation of a three-dimensional depth-semi-averaged model
(Journal article; Peer reviewed, 2019)The present work completes the validation of the depth-semi-averaged model defined in Antuono et al. [“A depth semi-averaged model for coastal dynamics,” Phys. Fluids 29, 056603 (2017)] providing a numerical implementation ... -
Vortex system around a step cylinder in a turbulent flow field
(Peer reviewed; Journal article, 2021)The vortex system around the step surface of a step cylinder with a diameter ratio D/d=2 at Reynolds number (ReD) 3900 was investigated by directly solving the three-dimensional Navier–Stokes equations. Formation mechanisms ...
