Dissolution and mixing of flavin mononucleotide in microfluidic chips for bioassay
Dissolution and mixing of flavin mononucleotide (FMN), which activates a luminescent reaction, were considered in various designs of microfluidic chip for pollution analysis of liquid samples. The aim was to determine the ...
Microconvection in vertical channel at given heat flux
A problem on stability of the viscous heat-conducting liquid flow in the vertical channel at given heat flux on the permeable solid walls is studied. The two-dimensional flow is described by an exact invariant solution of ...
Studying laminar flows of power-law fluids in the annular channel with eccentricity
The paper deals with numerical and experimental investigation of non-Newtonian flow of modeling drilling fluids in the annular channel. The Reynolds number was ranged from 100 to 1500. The parameters of the power-law model ...
Investigation of the additive effect of nanoparticles on the hydrodynamic characteristics of drilling fluids
Investigations of the rheological properties of drilling fluids based on nanoparticles are carried out. The dependences of the effective viscosity and rheological parameters of fluids on the concentration, size and material ...
Hybrid methods for simulating hydrodynamics and heat transfer in multiscale (1D-3D) models
The work is devoted to application of different-scale models in the simulation of hydrodynamics and heat transfer of large and/or complex systems, which can be considered as a combination of extended and "compact" elements. ...
Numerical and experimental study of the pressure pulsations at the free discharge of water through the turbine
The free discharge through the turbine is applied in the course of construction of hydro power plant or in case of excessive water inflow during floods or emergency situation. The experimental and numerical investigation ...
