A novel method for gamma spectrum analysis of low-level and intermediate-level radioactive waste
The uncertainty of nuclide libraries in the analysis of the gamma spectra of low- and intermediate-level radioactive waste (LILW) using existing methods produces unstable results. To address this problem, a no...

Direct numerical simulation of the viscoelastic channel flow using Giesekus model with variable parameters
The paper presents a direct numerical simulation (DNS) for the drag-reducing channel flow using the Giesekus model with variable parameters. It is assumed that the relaxation time in the constitutive equation ...

Turbulence Transport of Surfactant Solution Flow During Drag Reduction Degeneration
Turbulence transport of surfactant solution flow during drag reduction degeneration is investigated experimentally in a two-dimensional channel. Particle Image Velocimetry (PIV) system is used to take two-dime...

Effects of Temperature and Concentration on Rheological Characteristics of Surfactant Additive Solutions
The shear viscosity of turbulent drag-reducing surfactant solution was measured as a function of concentration, shear rate and temperature by using an AG-G2 rheometer (TA Instruments, New Castle, USA). The exp...
