Fluid Pressure over Curved Plate of Constant Width

Fluid Pressure over Curved Plate of Constant Width

When a curved plate of constant width is submerged in a liquid, the pressure acting normal to the plate varies continuously both in magnitude and direction. Calculating the magnitude and location of the resultant force at a point is often challenging for such cases. One of the methods to determine the resultant force and its location involves separately calculating the horizontal and vertical components of the resultant force. This complex calculation can be simplified by representing the...

Pressure Variation in a Fluid at Rest

Pressure Variation in a Fluid at Rest

In a fluid at rest, the pressure at any point beneath the fluid surface depends solely on the depth, not on the container's shape or size. This principle, known as hydrostatic pressure, arises because, in stationary fluids, there is no acceleration, meaning the forces within the fluid balance out. Only vertical forces, caused by the weight of the fluid above, contribute to pressure changes with depth.
When measuring pressure at two different levels within the fluid, the difference in pressure...

Magnetostatic Boundary Conditions

Magnetostatic Boundary Conditions

An electric field suffers a discontinuity at a surface charge. Similarly, a magnetic field is discontinuous at a surface current. The perpendicular component of a magnetic field is continuous across the interface of two magnetic mediums. In contrast, its parallel component, perpendicular to the current, is discontinuous by the amount equal to the product of the vacuum permeability and the surface current. Like the scalar potential in electrostatics, the vector potential is also continuous...

Conservation of Mass in Finite Cotrol Volume

Conservation of Mass in Finite Cotrol Volume

The principle of conservation of mass is a fundamental law in fluid mechanics and is applied using the continuity equation. We apply the concept to a finite control volume to derive the continuity equation.
A system is defined as a collection of unchanging contents, and the conservation of mass states that a system's mass is constant.

Fluid Pressure over Flat Plate of Constant Width

Fluid Pressure over Flat Plate of Constant Width

When a body is submerged in water, it experiences fluid pressure acting normal on its surface and distributed over its area. For better design structures, it is crucial to determine the magnitude and location of the resultant force acting on the surface. In the case of a rectangular plate of constant width submerged in water, the pressure increases with depth, resulting in a linearly varying trapezoidal pressure distribution from the upper to the lower edge of the plate.
The resultant force...

Fluid Pressure over Flat Plate of Variable Width

Fluid Pressure over Flat Plate of Variable Width

When a flat plate is submerged in a fluid, the fluid exerts pressure on the plate. This pressure can lead to many different phenomena, including drag and buoyancy. To understand the behavior of the fluid over a flat plate of variable width, it is essential to analyze the distribution of the pressure exerted.
The pressure distribution on the plate can be calculated by determining the force that acts on a differential area strip of the plate. Thus, the magnitude of the force is equal to the...

Area of Science:

Computational fluid dynamics
Numerical methods for fluid flow
Fluid-structure interaction

Background:

Simulating moving boundary problems with immersed boundary methods (IBMs) often leads to spurious pressure oscillations.
These oscillations are primarily caused by violations of the geometric conservation law near the immersed boundary.

Purpose of the Study:

To develop a method that reduces spurious pressure oscillations in sharp-interface immersed boundary simulations.
To maintain the desirable properties of finite-difference based IBMs while enhancing stability.

Main Methods:

A cut-cell based approach is adopted to strictly enforce geometric conservation near the immersed boundary.
The cut-cell discretization is selectively applied to pressure Poisson and velocity correction equations within a fractional-step method.
A virtual cell-merging technique is employed to address challenges associated with small cells.

Main Results:

The proposed method effectively reduces spurious pressure oscillations by approximately one order of magnitude.
The technique preserves the beneficial characteristics of the original finite-difference based IBM.

Conclusions:

The novel cut-cell approach provides a stable and accurate solution for simulating moving boundary flow problems.
This method enhances the reliability of immersed boundary simulations, particularly for applications involving dynamic boundaries.
