Bingham Fluid Flow in the Entrance Region of a Pipe

Journal of Fluids Engineering, 2020
AbstractLaminar Bingham fluid flow in the entrance region of a circular pipe is investigated using a momentum integral model. The fully developed flow is uniform in the core region, while the velocity changes in the annular part of the cross section of the pipe. The inlet-filled region concept is adopted.

Laminar flow in the entrance region of a pipe

Applied Scientific Research, 1964
The laminar flow of an incompressible fluid in the inlet of a pipe is analyzed numerically. The numerical technique allows a closer approximation to the basic equations of fluid motion than has been possible in previous investigations. Significant differences are shown between the results of the numerical solution and previous work for both velocity ...

Coupled radiation, conduction and convection in entrance region flow

International Journal of Heat and Mass Transfer, 1966
Abstract An analytical procedure is developed to investigate the interaction or coupling of radiation with the conduction and convection mechanism in a nonisothermal, nongray gas flowing in the entrance region of a tube with isothermal, black walls. The flow is considered to be hydrodynamically developed and laminar.

Deposition of suspensions in the entrance region of a vertical channel

Powder Technology, 1980
Abstract The deposition of aerosols with gravity in a vertical channel from the inlet to a distance of 50 channel widths was investigated numerically for developing, fully developed, and uniform laminar flows. The relative importance of sedimetation as compared to Brownian diffusion was determined by the parameter σ = vgh/D where vg is the settling ...

Turbulent Heat Transfer in the Entrance Region of a Tube

Heat Transfer Engineering, 1982
Correlation of the data for heat transfer between a fluid in turbulent flow and the entrance region of a tube is made for the entrance shapes normally used in heat exchangers. Equations representing the variation of the “average heat transfer” with tube length, Reynolds number, and Prandtl number are suggested.

Turbulent Pulsating Flow in the Entrance Region of a Pipe

1981
The effect of flow pulsations on the characteristics of turbulent flow in the entrance region of a cylindrical pipe is presented. A velocity wave which causes local friction in the turbulent boundary layer is observed in the core flow for relative amplitude of flow fluctuations of 15%.

Hydrodynamic Entrance-Region Flow of Pseudoplastic Fluids

Proceedings of the Institution of Mechanical Engineers, 1974
The hydrodynamic entrance-region flow of pseudoplastic liquids is studied by solving both the differential and integral equations of the boundary-layer flow simultaneously by extending the procedure of Fargie and Martin. The results are strictly applicable in the high Reynolds number region only.

Laminar heat transfer in the thermal entrance region

The Canadian Journal of Chemical Engineering, 1970
AbstractSeries solutions for heat transfer in the thermal entrance region are presented for laminar flow in conduits (plane ducts, tubes, annular passages). The present solution of the equation of energy has been obtained for either a step change in heat flux or wall temperature and is valid for all time‐independent non‐Newtonian fluids, providing that
