Third sound dissipation at a point contact

Vortex Dissipation in Superfluid Third Sound Flows

Fluctuation and dissipation at a quantum critical point.

In nonrelativistic field theories, quantum fluctuations give rise to dissipative behavior even at zero temperature. Here we use holographic methods to explore the dissipative dynamics of massive particles coupled to quantum critical theories. We present analytic expressions for correlation functions and response functions. The behavior changes qualitatively as the dynamical exponent passes thro...

Frictional Energy Dissipation in a Rough Hertzian Contact

The interfacial contact pressure and shear traction distributions are found for a sphere pressed onto an elastically similar half-space whose surface is populated by a uniform array of spherical asperities, when the normal load is constant and an oscillatory shear, less than that needed to cause sliding, is imposed. Details of the load history suffered by asperities in an outer sliding annulus ...

Melting Heat Transfer in the Stagnation-point Flow of Third Grade Fluid past a Stretching Sheet with Viscous Dissipation

An analysis has been carried out for the characteristics of melting heat transfer in the boundary layer flow of third grade fluid in a region of stagnation point past a stretching sheet. The relevant partial differential equations are reduced into ordinary differential system by suitable transformations. The series solutions are developed by homotopy analysis method. It is revealed that an incr...
