aThe velocity used in the force equation is evaluated at each integration step by linear interpolation within the appropriate segment. 用于力量等式的速度在适当的段之内被评估在每综合化步由线性插值法。 [translate] 英语翻译 日语翻译 韩语翻译 德语翻译 法语翻译 俄语翻译 阿拉伯语翻译 西班牙语翻译 葡萄牙...
In the following equations, p, v, ρ, t, c, and u are the acoustic pressure (the local deviation from the ambient pressure), velocity, density, time, the speed of sound, and the vector field particle velocity respectively. Also, terms with only a zero index or a combination of multiply...
If an object moves through a fluid, it experiences a resisting force, the drag force. The value of this force depends on the size and shape of an object, the density of the fluid, and the relative velocity of the object and the fluid. The equation is: Fd = 1/2 ×ρ× u² × ...
and the corresponding kinetic energy: KE=12mv2KE=21mv2 Newton's universe — arrive at the destination and stop In this situation, we accelerate to the halfway point, reach maximum velocity, and then decelerate to stop at the destination point. Distance covered during the same time is, as ...
The linearized wave equation was developed in Chapter 3 on the basis that the fluid element considered was not subject to any external force, did not receive or lose heat or fluid mass, and suffered no intrusion through the action of external agents. The solutions of the equation therefore ...
We show that these meshless methods are trained by smaller amount of data and can predict the solution of the equation with even high accuracy. They are also capable of inverting any parameter involved in the governing equation such as wave velocity in our case. Results show that the GP can...
where [𝑢,𝑎,𝑏,𝑒,𝑓,𝜉,𝑢3] represent a displacement in time, linear stiffness, the amount of nonlinearity in the regenerating force, a quantity of damping, the amplitude of the repeated driving force, the angular frequency of the occasional driving force, and the Duffing term,...
,where u is the fluid velocityvector,Pis the fluidpressure, ρ is the fluiddensity, and ∇ indicates thegradientdifferential operator. The Navier-Stokes equation, in modern notation, is ,where u is the fluid velocityvector,Pis the fluid pressure, ρ is the fluid density, υ is the kinemati...
inertia, andω, theangular velocity, of a rotating body or system, or simplyIω. When the rotation is aligned with one of a body’s principalaxes, the direction of the angular-momentum vector is that of the axis of rotation of the given object and is designated as positive in the direc...
