In computational fluid dynamics, the projection method, also called Chorin's 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 .
ANSI/AMCA Standard 220 - Laboratory Methods of Testing Air Curtain Units For Aerodynamic Performance Rating establishes uniform methods for laboratory testing of air curtain units to determine aerodynamic performance in terms of airflow rate, outlet air velocity uniformity, power consumption and air velocity projection for rating or guarantee ...
The method is sometimes called minor loop synthesis in college textbooks, [1] [2] some government documents. [3] The method is suitable for design by graphical methods and was used before digital computers became available. In World War 2 this method was used to design gun laying control systems. [4] It is still used now, but not always ...
Dykstra's algorithm is a method that computes a point in the intersection of convex sets, and is a variant of the alternating projection method (also called the projections onto convex sets method). In its simplest form, the method finds a point in the intersection of two convex sets by iteratively projecting onto each of the convex set; it ...
John "Shôn" Eirwyn Ffowcs Williams FRSA FRAeS FInstP FREng [1] [7] [8] [a] (25 May 1935 – 12 December 2020) was Emeritus Rank Professor of Engineering at the University of Cambridge and a former Master of Emmanuel College, Cambridge (1996–2002). [9] He may be best known for his contributions to aeroacoustics, in particular for his work on ...
Projection (set theory), one of two closely related types of functions or operations in set theory; Projection (measure theory), use of a projection map in measure theory; 3D projection, any method of mapping three-dimensional points to a two-dimensional plane; Vector projection, orthogonal projection of a vector onto a straight line
The study of the hodograph, as a method of investigating the motion of a body, was introduced by Sir W. R. Hamilton. The hodograph may be defined as the path traced out by the extremity of a vector which continually represents, in direction and magnitude, the velocity of a moving body.
Velocimetry is the measurement of the velocity of fluids. This is a task often taken for granted, and involves far more complex processes than one might expect. It is often used to solve fluid dynamics problems, study fluid networks, in industrial and process control applications, as well as in the creation of new kinds of fluid flow sensors.
