Kinetic Theories for Nonisothermal Flows: Differential Constitutive Equations,uses anisotropic drag to incorporate interactions between polymer molecules; the resulting constitutive equation is the nonisothermal form of the Giesekus equation. The constitutive equation thus obtained differs from that which would be obtained by applying the pseudo-time postulate to the isothermACE-inhibitor 发表于 2025-3-27 03:49:28
Micro-Rheological Modelling of Heat Conduction in Polymeric Liquids,nductivity tensor to the deformation history of an amorphous polymeric material are presented. The first model is based upon the network theory for polymers and the second model is based upon kinetic theory. Despite the fact that the models are relatively simple there is good agreement with the spar送秋波 发表于 2025-3-27 06:40:25
Thermorheological Modelling of Viscoelastic Materials, constitutive models and offers the possibilty to investigate and extend these models in a systematic way. Modelling starts with an expression for the stress tensor in terms of the microstructure and the principal nonaffine motion thereof. Finally, however, equations are formulated in macroscopic te滴注 发表于 2025-3-27 13:09:58
Numerical Simulation of a Viscoelastic Fluid with Anisotropic Heat Conduction,e constitutive equation for the stress. In the energy equation the heat flux is specified by Fourier’s law, where anisotropic heat conduction has been taken into account. Furthermore one has to specify which part of the stress work is dissipated and which part is stored as elastic energy. The equati去才蔑视 发表于 2025-3-27 16:04:18
Oscillations in Piston-Driven Shear Flow of a Non-Newtonian Fluid,c oscillations in the particle velocity at the channel wall for particular values of the constant volumetric flow rate. Such periodicity has been characterized as a “stick/slip” phenomenon caused by the failure of the fluid to adhere to the wall. We suggest an alternative explanation for these oscil诱惑 发表于 2025-3-27 21:18:35

Numerical Simulation and Experimental Results on Thermo-Elasto-Hydrodynamic Tilting-Pad Journal Beaequation and the energy equation in the film, and the heat transfer equation in the material. The thermoelastic displacements of all bearing elements are also calculated. The four-shoe tilting-pad journal bearing is studied theoretically and the results are compared with the experimental data. The t狗窝 发表于 2025-3-28 04:12:29
Non-Isothermal Effects in Capillary Viscometry,This is because the flow in the capillary is assumed to be at a constant temperature. The implications of viscous dissipation for viscometry are investigated by numerically simulating the flow in a capillary viscometer using a finite difference discretization of the governing equations of motion.

Numerical Modelling of Nonisothermal Viscoelastic Flow between Eccentrically Rotating Cylinders,onditions and different values of eccentricity. The constitutive model employed is a White-Metzner fluid, with a viscosity and single relaxation time both of which are shear thinning, temperature thinning and pressure thickening. A pseudospectral method with bipolar transformation is used for spatia
