Irrotational Flow01:28

Irrotational Flow

Irrotational flow is characterized by fluid motion where particles do not rotate around their axes, resulting in zero vorticity. For a flow to be irrotational, the curl of the velocity field must be zero. This imposes specific conditions on velocity gradients. For instance, to maintain zero rotation about the z-axis, the gradient condition:
Turbulent Flow01:24

Turbulent Flow

Turbulent flow is characterized by unpredictable fluctuations in velocity and pressure, which result in a chaotic fluid movement distinct from the orderly patterns of laminar flow. While laminar flow is governed by smooth, parallel layers with minimal mixing, turbulent flow exhibits highly irregular, three-dimensional patterns. This behavior arises due to instabilities in the fluid's velocity profile, and amplifies as the flow velocity increases. Minor disturbances, known as turbulent spots,...
Couette Flow01:22

Couette Flow

Couette flow represents the flow of fluid between two parallel plates, with one plate fixed and the other moving with a constant velocity. This configuration allows for a simplified analysis using the Navier-Stokes equations, which govern fluid motion under conditions of viscosity and incompressibility. For Couette flow, the assumptions include a steady, laminar, incompressible flow with a zero-pressure gradient in the flow direction. This flow type is beneficial for understanding shear-driven...
Thin-Walled Hollow Shafts01:15

Thin-Walled Hollow Shafts

In analyzing a thin-walled hollow shaft subjected to torsional loading, a segment with width dx is isolated for examination. Despite its equilibrium state, this segment faces torsional shearing forces at its ends. These forces are quantitatively described by the product of the longitudinal shearing stress on the segment's minor surface and the area of this surface, leading to the concept of shear flow. This shear flow is consistent throughout the structure, indicating a uniform distribution of...
Turbulent Flow: Problem Solving01:09

Turbulent Flow: Problem Solving

Carbonation is a process used to dissolve carbon dioxide gas in a liquid, commonly used in the production of carbonated beverages. Achieving efficient carbonation requires careful control of temperature, pressure, and flow conditions. By adjusting these parameters, carbonation efficiency can be maximized, producing a higher concentration of CO2 in the liquid.
Temperature is a key factor in CO2 solubility. In this case, the CO2 gas and the liquid are cooled to 20°C. Lower temperatures enhance...
Steady, Laminar Flow Between Parallel Plates01:17

Steady, Laminar Flow Between Parallel Plates

Understanding steady, laminar flow between parallel plates is essential for analyzing and designing flow in narrow rectangular channels, commonly found in various water conveyance and drainage systems. The Navier-Stokes equations govern fluid motion and are generally challenging to solve due to their nonlinearity. However, simplifications are possible in certain cases, like the steady laminar flow between parallel plates. For this scenario, we assume steady, incompressible, laminar flow.

Area of Science:

  • Fluid Dynamics
  • Multiphase Flow
  • Vortex Dynamics

Background:

  • Vortex breakdown (VB) is a complex flow phenomenon crucial in various engineering applications.
  • Previous studies primarily focused on axisymmetric or wall-bounded vortex breakdown.
  • The behavior of VB in two-fluid systems under rotation remains less understood.

Purpose of the Study:

  • To investigate the off-axis emergence of vortex breakdown in a rotating two-fluid system.
  • To analyze the influence of rotation speed and fluid interface position on VB characteristics.
  • To characterize the development of VB in both water and air regions.

Main Methods:

  • Numerical simulations of a steady axisymmetric flow in a vertical sealed cylinder.
  • The cylinder is partially filled with water and driven by a rotating bottom disk.
  • Analysis of flow patterns at varying rotation speeds and water heights.

Main Results:

  • Vortex breakdown (VB) was observed to emerge off-axis, away from the rotation axis, interface, and walls.
  • VB initially forms in the water region and its location (on- or off-axis) depends on water height relative to cylinder radius.
  • Increasing rotation leads to the off-axis VB ring interacting with the interface, forming a counter-circulation layer in the air.

Conclusions:

  • The study demonstrates the possibility of off-axis vortex breakdown in a rotating two-fluid system.
  • Fluid interface dynamics significantly influence the structure and behavior of vortex breakdown.
  • The findings provide new insights into complex vortex dynamics in partially filled rotating cylinders.
