Numerical analysis of a non-clamped dynamic thermoviscoelastic contact problem

, 2019
In this work we analyze a non-clamped dynamic viscoelastic contact problem involving thermal effect. The friction law is described by a nonmonotone relation between the tangential stress and the tangential velocity.

Numerical modeling of wall-to-cluster heat transfer in swirling fluidized beds based on MFiX-DEM approach

Case Studies in Thermal Engineering
The introduction of a tangential velocity component in swirling fluidized beds enhances mixing and heat transfer. Particle clusters are common mesoscale structures in gas-solid flow systems.

Relationship between Axial Width and Flow Characteristics of Pump Chamber in Double Volute Centrifugal Pump

Xibei Gongye Daxue Xuebao, 2020
The axial width of pump chamber has a great influence on the flow characteristics of the pump chamber in the centrifugal pump. A single-stage single-suction double volute centrifugal pump with a semi-open impeller was selected as the object.

An ADCP Attitude Dynamic Errors Correction Method Based on Angular Velocity Tensor and Radius Vector Estimation

Journal of Marine Science and Engineering
An acoustic Doppler current profiler (ADCP) installed on a platform produces rotational tangential velocity as a result of variations in the platform’s attitude, with both the tangential velocity and radial orientation varying between each pulse’s ...

The pressure tensor in tangential equilibria [PDF]

Annales Geophysicae, 2004
The tangential equilibria are characterized by a bulk plasma velocity and a magnetic field that are perpendicular to the gradient direction. Such equilibria can be spatially periodic (like waves), or they can separate two regions with asymptotic ...

Flow of Fluids with Pressure-Dependent Viscosity in Between Intersecting Planes

Fluids
The flow of an incompressible power-law fluid through a convergent channel is considered, where the viscosity is chosen to be pressure dependent. Instead of utilizing the classical similarity transformation traditionally employed when considering Jeffery-
