Hi dear list Do you know that there is a torque in all gases when there is a rotation in them? The rotation causes the molecule to experience different centrifugal forces when going forwards or backwards in the direction of flow. This effectively is experienced as a torque that in combination with the rotation is either a loss or gain of power. It might seems identical to viscosity but it is not. The effect is present even in solid body rotation which viscosity is not.
Since viscosity is a kinetic gas theory term it only works in inertial systems. This means that the Navier-Stokes equations only works in inertial systems. I have shown that the complexity in a usual case can be compensated for by adding a torque term. Have you ever heard of anyone investigating this phenomena? I calculated the torque for NTP conditions on Earth and found the torque to be -0.3 nNm per mole. Negative sign means that the torque opposes the rotational direction of the flow. After 20 GMT on Wednesday you can check the calculation. I am trying to calculate for other known planets too. The problem is to find data for those planets. Since the torque is negative it could only basically explain the retrograde winds of Neptune and partially retrograde winds of Jupiter. I found that one way to find a balancing torque is to see if the torque is of similar strenght as the torque from the shear necessarry to cause the shear Couette flow on for example Jupiter. http://en.wikipedia.org/wiki/File:Wind_speeds_on_Jupiter.png The shear in the flow is τ = µ ∂u/∂y . Any help welcome. I am also considering analyzing some vortex and Schauberger phenomena to see what this torque is in these cases. Please give me details if you have. What I need to know is temperature, gas constituents and velocity field and size of the noticed viscosity loss. It would be very funny to see if the apparent loss of viscosity actually is due to this torque effect. David David Jonsson, Sweden, phone callto:+46703000370
