friction and
Much more attention has been paid to the tribo-electrochemical mechanisms for the control of friction and wear.
      
This problem was examined in part in [1], in which the distribution of the friction and pressure in a region with length on the order of a few thicknesses of the approaching boundary layer was obtained in the first approximation.
      
A relationship is also derived between turbulent friction and the mean velocity profile on the basis of the equation for the maximum turbulent friction, which follows directly from the equation of motion.
      
Effect of transport processes in the laminar sublayer on friction and heat transfer in the nonequilibrium dissociating turbulent
      
The coefficients of friction and heat transfer, and the inclination of the bottom flow lines are averaged.
      
Friction and heat exchange in turbulent flow of weak polymer solutions in smooth pipes
      
A scheme to compute the friction and heat-transfer coefficients for a fluid flow with polymer admixtures to reduce friction, based on the mixing-path-length representation, is proposed.
      
The effect of the particles on friction and heat transfer is analyzed on the basis of the equations of two-fluid theory.
      
The simplest model accounting for the effect of the particles on friction and heat transfer for the general case, when the particles are not in equilibrium with the gas at the outer edge of the boundary layer, is Couette flow.
      
The question of the applicability of the "quasistationary" approach to calculation of the friction and the dissipative loss in unsteady flow is discussed.
      
The motions of Newtonian and non-Newtonian media with consideration of the heat of friction and temperature dependence of the rheological characteristics of the medium have been examined by many authors [1-6].
      
Friction and heat transfer in a laminar boundary layer with periodic pressure fluctuations
      
The thin-wall region - the laminar (or viscous) sublayer, in which the molecular mechanism of transfer predominates - plays an important role in friction and heat-transfer processes in a turbulent boundary layer.
      
Expressions are obtained for the coefficients of friction and heat transfer on the surface of the body, and also for the profiles of the velocities and the temperature across the shock layer.
      
Calculation of friction and heat and mass exchange on rough permeable plane and axisymmetric bodies
      
The method makes it possible to calculate the characteristics of a turbulent boundary layer, including friction and heat transfer, without separation of discontinuities and special regions and to do this in both attached and separated flow regions.
      
Influence of nonuniformity of supersonic flow with shock waves on the friction and heat transfer in planar channels
      
A numerical investigation has been made of the influence of nonuniformity of a supersonic flow with shock waves on the friction and heat transfer in planar channels.
      
Friction and heat transfer in laminar and turbulent boundary layers on axisymmetric bodies in nonuniform supersonic flows
      
Generalized dependences are obtained for the coefficients of friction and heat transfer on the impermeable boundary.
