Casimir force




by RedGuff » 15/07/10, 17:37

Bonjour.
I want to know if the force of Casimir decreases when the velocity varies perpendicular or tangential to the perpendicular to the plates.
I want to know if the force of Casimir decreases a lot when the angle between the plates varies a little.
Goods.
My idea is a multi-stage rotor and stator reel, similar to turbines.

An exact answer is very complex, but the force with the speed will vary only in (tangential speed on the speed of the light) with a power to be verified but in my opinion equal to 2, for two infinite planes, is very little.
But with finished planes the variation is related to the variation of the facing surfaces and the edges effects.
Finally it varies with the angle to the minimum as the local distance variations stronger at short distance, and therefore it increases, if we keep the average distance.

Finally Casimir's force for two short-range molecules is called the Van der Walls force, which is the cause of the solid, liquid and vapor transitions and therefore a steam engine works with the force of Casimir, as Monsieur Jourdain was doing prose without knowing it !!
So this force is nothing special at the practical level, it respects thermodynamics, except that quantum mechanics required to calculate, is surprising with the possibility for a particle to be in several places at once in the form of wave and particle at a time.

Use Derjaguin's formula 46 to calculate the effect of an angle (instead of a sphere in front of a plane)

Remarkable special case of Casimir's strength becoming repulsive in a liquid !!

Van der Walls force and Casimir effect are different.

Bonjour.
Van der Walls force and Casimir effect are different.
The "expansive force of steam" and the force of Van der Walls Force are different.
