چکیده
The dimensioning of injection heads for the extrusion of rubber profiles is exclusively based on empiric knowledge of the non-linear flow behaviour of elastomers. Thus, the design of injection heads is carried out with subject to the used rubber blend, whereas the geometry of the appropriate profile is achieved by empiric adaptation of the extrusion die. This was one of the motivations for a research project concerning the experimental and numerical characterisation of the shear rate dependent viscosity of rubber blends.

Evaluation of Recirculation Time in Bubble Train Flow by Using Direct Numerical Simulation
In this research, hydrodynamics of the Bubble Train Flows (BTF) in circular capillaries has been investigated by Direct Numerical Simulation (DNS).The Volume of Fluid Based (VOF) interface tracking method and streamwise direction periodic boundary conditions has been applied. The results show that there exists an appropriate agreement between DNS and experimental correlation results. The re...
متن کاملMathematical Analysis of MHD Flow of Blood in Very Narrow Capillaries (RESEARCH NOTE)
A mathematical model for blood flow in narrow capillaries under the effect of transverse magnetic field has been investigated. It is assumed that there is a lubricating layer between red blood cells and tube wall. The transient flow of the fit red blood cell surrounded by plasma annulus in the narrow capillary is considered. The analysis of fluid flow between red cell and tube wall, when the ce...

Background: Neuropathy is one of the important complications of diabetes. Deficiency of the nerve conduction velocity (NCV) that occurs in both human diabetic neuropathy and animal diabetes models is one of the indicators for diabetic neuropathy. In the present study, we examined the effect of enalapril, angiotensinconverting enzyme inhibitor on NCV, number of endoneurial capillaries and th...

Due to high resolution power of sulfated cyclodextrins (HS-CDs), utilization of these selectors for chiral resolution of 7 basic and 2 zwitterionic drugs have been examined. Experiments were performed on a HP3DCE instrument equipped with an on-column diode array UV absorbance detector. Fused silica capillaries with an inner diameter of 50 ?m, an outer diameter of 365 ?m, and a total length of 4...
