Planes in Space01:31

Planes in Space

A plane in three-dimensional space is fundamentally characterized by a point that lies on the plane and a normal vector that is perpendicular to its surface. This normal vector uniquely determines the orientation of the plane, making it an essential geometric descriptor. In architectural applications, such as the installation of a sloped glass panel on a building façade, this mathematical model provides a precise representation of the panel’s position and orientation in space.Let r₀ be the...
Tangent Planes to Surfaces01:19

Tangent Planes to Surfaces

In multivariable calculus, the concept of a tangent plane plays a central role in approximating curved surfaces. When dealing with a surface defined by a function of two variables, such as z = f(x, y), the tangent plane at a given point provides the best linear approximation to the surface near that point. This local linearization allows complex, nonlinear geometries to be treated using simpler, planar models.The construction of the tangent plane involves taking vertical slices of the surface...
Gravity between Spherical Bodies01:27

Gravity between Spherical Bodies

Newton's law of gravitation describes the gravitational force between any two point masses. However, for extended spherical objects like the Earth, the Moon, and other planets, the law holds with an assumption that masses of spherical objects are concentrated at their respective centers.
This assumption can be proved easily by showing that the expression for gravitational potential energy between a hollow sphere of mass (M) and a point mass (m) is the same as it would be for a pair of extended...
Hydrostatic Pressure Force on a Plane Surface01:04

Hydrostatic Pressure Force on a Plane Surface

When a plane surface is submerged in a fluid, hydrostatic forces develop on the surface due to the fluid's pressure. For horizontal surfaces, the pressure exerted by the fluid is uniform because the depth remains constant. The resultant force is determined by the pressure at the given depth multiplied by the area of the surface, and it acts through the centroid of the surface. For vertical surfaces, the pressure varies with depth, increasing as the distance from the fluid's free surface...
Tangent Planes to Level Surfaces01:31

Tangent Planes to Level Surfaces

A level surface consists of all points in space where a function of three variables takes the same fixed value. If a point lies on this surface, understanding the surface’s geometry there requires more than just knowing the point’s coordinates; it requires describing how the surface is oriented, or how it tilts, near that point.To probe this local geometry, imagine tracing a path that stays entirely on the level surface and passes through the point of interest. This path can be described as a...
Mohr's Circle for Plane Strain01:18

Mohr's Circle for Plane Strain

Mohr's circle is a crucial graphical method used to analyze plane strain by plotting strain on a set of cartesian coordinates, where the abscissa is normal strain ∈ and the ordinate is shear strain γ. Similarly to Mohr’s circle for plane stress, two points X and Y are plotted. Their coordinates are (∈x, -γXY) and (∈Y, γXY), respectively.
Mohr's circle visually represents the strain states under various conditions, which is essential for understanding material behavior. The center of Mohr's...

Summary

Cavitation causes irreversible hydrodynamic effects for spheres near walls, deviating from classical theory. Experimental data confirms this cavitation-induced irreversibility in sphere motion.

Area of Science:

  • Fluid dynamics
  • Hydrodynamics
  • Cavitation physics

Background:

  • Classical continuum theory fails to predict sphere motion near walls.
  • Surface roughness was previously thought to cause irreversibility.
  • Cavitation occurs when pressure drops to vapor pressure.

Purpose of the Study:

  • Investigate hydrodynamic irreversibility for spheres near a wall.
  • Examine the role of cavitation in sphere motion.
  • Validate theoretical predictions of cavitation effects.

Main Methods:

  • Experimental observation of sphere motion under gravity.
  • Analysis of hydrodynamic behavior near a solid wall.
  • Inducing cavitation by pressure drop.

Main Results:

  • Observed irreversibility in sphere velocity not explained by continuum theory.
  • Cavitation was induced between the sphere and the wall.
  • Experimental data aligns with theoretical predictions including cavitation.

Conclusions:

  • Cavitation is a key factor in the observed hydrodynamic irreversibility.
  • Classical continuum theory is insufficient for near-wall sphere dynamics with cavitation.
  • The irreversible effect of cavitation accurately predicts sphere motion.
