It has become a well-known fact that finding sustainable solutions to the unavoidable high
pressure losses accompanying pipeline flows to increase the pumping capacity without …

The current work qualitatively surveys the phenomenon of polymer drag reduction from the
standpoint of the salient coherent motions in the near-wall region of wall-bounded turbulent …

This article presents a new turbulence closure based on the k-ω SST model for predicting
turbulent flows of Herschel–Bulkley fluids, including Bingham and power-law fluids. The …

The paper presents a novel Reynolds-averaged turbulence model for flows of power-law
fluid. The model uses the elliptic relaxation approach to capture the near-wall turbulence …

The conveyance of fluids from one terminal to another incurs considerable expenses
primarily due to the significant costs associated with addressing pressure losses arising from …

A new low-Reynolds-number k–ε turbulence model is developed for flows of viscoelastic
fluids described by the finitely extensible nonlinear elastic rheological constitutive equation …

This work introduces a mathematical approach to analysing the polymer dynamics in
turbulent viscoelastic flows that uses a new geometric decomposition of the conformation …

Particle image velocimetry (PIV) measurement technique provides an excellent opportunity
for investigating instantaneous spatial structures which are not always possible with point …

A tensorially consistent near-wall four equation model is developed to model turbulent flow
of dilute polymer solutions. The model is validated up to the maximum drag reduction limit …

A mathematical model of the movement and heat transfer of a turbulent non-isothermal non-
Newtonian fluid through a pipe wall with a cold surrounding space has been developed and …
