Correction of refractive errors by glasses; Prism therapy (if tolerated, to manage diplopia) Vision Therapy; Patching (mainly to manage amblyopia in children and diplopia in adults) Botulinum toxin injection; Surgical correction; Surgical correction of the hypertropia is desired to achieve binocularity, manage diplopia and/or correct the ...
In thermodynamics, the Volume Correction Factor (VCF), also known as Correction for the effect of Temperature on Liquid (CTL), is a standardized computed factor used to correct for the thermal expansion of fluids, primarily, liquid hydrocarbons at various temperatures and densities.
Pressure prism. A pressure prism is a way of visually describing the variation of hydrostatic pressure within a volume of fluid. When variables of fluid density, depth, gravity, and other forces such as atmospheric pressure are charted, the resulting figure somewhat resembles a prism .
Pressure-correction method is a class of methods used in computational fluid dynamics for numerically solving the Navier-Stokes equations normally for incompressible flows.
PISO algorithm ( Pressure-Implicit with Splitting of Operators) was proposed by Issa in 1986 without iterations and with large time steps and a lesser computing effort. It is an extension of the SIMPLE algorithm used in computational fluid dynamics to solve the Navier-Stokes equations. PISO is a pressure-velocity calculation procedure for the ...
In fluid dynamics, The projection method is an effective means of numerically solving time-dependent incompressible fluid-flow problems. It was originally introduced by Alexandre Chorin in 1967 [1] [2] as an efficient means of solving the incompressible Navier-Stokes equations. The key advantage of the projection method is that the computations ...
Volumetric flux. In fluid dynamics, the volumetric flux is the rate of volume flow across a unit area (m 3 ·s −1 ), and has dimensions of distance/time (volume/ (time*area)) - equivalent to mean velocity.
An illustration of fluid simulation using VOF method. In computational fluid dynamics, the volume of fluid (VOF) method is a free-surface modelling technique, i.e. a numerical technique for tracking and locating the free surface (or fluid–fluid interface ). It belongs to the class of Eulerian methods which are characterized by a mesh that is ...
Discretization of the Navier–Stokes equations of fluid dynamics is a reformulation of the equations in such a way that they can be applied to computational fluid dynamics. Several methods of discretization can be applied: Finite volume method; Finite elements method; Finite difference method
Numerical Methods in Fluid Mechanics. Fluid motion is governed by the Navier–Stokes equations, a set of coupled and nonlinear partial differential equations derived from the basic laws of conservation of mass, momentum and energy. The unknowns are usually the flow velocity, the pressure and density and temperature. The analytical solution of ...
