This work encompasses together a number of diverse disciplines (physiology, biomechanics, fluid mechanics and simulation) in order to develop a predictive model of the behaviour of a prosthetic heart valve in vivo. The application of simulation, for the study of other cardiovascular problems, such as blood clotting is also discussed. A commercial, finite volume, computational fluid dynamics (CF...

This Master’s Thesis compares two computational fluid dynamics solvers: the commercial solver ANSYS CFX and the open source code OpenFOAM. Simple benchmark cases with compressible and incompressible flows are tested and compared. Thereafter the more complex process of quenching in coal gasification is simulated. This thesis work describes the simulation of a part of the coal gasification proces...

OBJECTIVE This study aimed to assess the incidence of coronary anomalies using 64-multi-slice coronary computed tomography (MSCT). METHODS The diagnostic MSCT scans of 745 consecutive patients were reviewed. RESULTS The incidence of coronary anomalies was 4.96%. The detected coronary anomalies included the conus artery originating separately from the right coronary sinus (RCS) (n = 8, 1.07%...

The enhancement of the fluorination degree carbon fluorides (CFx) compounds is most effective method to improve energy densities Li/CFx batteries because specific capacity CFx proportional molar ratio F C atoms (F/C). In this study, B-doped graphene (BG) prepared by using boric acid as doping source and then BG utilized starting material for preparation CFx. B-doping enhances F/C without hinder...

The large-scale, multi-compartment PANDA facility (located at PSI in Switzerland) is one of the stateof-the-art facilities which is continuously upgraded to progressively match the requirements of CFD-grade experiments. Within the OECD/SETH projects, the PANDA facility has been used for the creation of an experimental database on basic containment phenomena e.g. gas mixing, transport, stratific...

The present paper discusses the pressure loss through the spiral heat exchanger (HX) proposed in the ELSY (European-Lead cooled SYstem) project. An approach based on CFD (Computational Fluid Dynamics) using the commercial code ANSYS CFX has been used for exploring the flow through the HX. The HX consists of perforated double inner and double outer walls, as well as an innovative spiral design o...

For more than 40 years, electrical stimulation procedures for unilateral recurrent laryngeal nerve paresis (URLNP) therapy have been proposed. However, it is unclear whether electrical stimulation therapy is effective for URLNP patients. In this study we compare the outcome of traditional voice exercise treatment (VE) with electrical stimulation-supported voice exercise (ES). A total of 90 URLN...

Graphite fluoride (CFx) cathodes coupled with lithium anodes yield one of the highest theoretical energy densities (>860 Wh/g) among primary batteries. In practice, observed discharge voltage (~2.5 V) is significantly lower than thermodynamic limits (>4.5 V), rate low, and so far Li/CFx has only been used in Understanding mechanism at atomic length scales will improve practical CFx density, cap...

Background and purpose: Recently, release of pollutants such as pharmaceuticals to the environment becomes one of the most important problems for soil and water. The present study was conducted to introduce walnut shell-based activated carbon (AC) as a new low-cost adsorbent for the removal of cephalexin (CFX) antibiotic from aqueous solutions. Materials and Methods: This study was conducted...
