An accuracy analysis of the front tracking method and interface capturing methods for the solution of heat transfer problems with phase changes
(IOP Publishing, 2016-06-19)Materials undergoing a phase change have a number of applications in practice and engineering. Computer simulation tools are often used for investigation of such heat transfer problems with phase changes since they are ... -
Comparison of turbulent models in the case of a constricted tube
(EDP Sciences, 2016-11-15)The validation of a proper solution is an indispensable phase of every numerical simulation. Nowadays, many turbulent models are available, whose application leads to slightly different solution of flow behaviour depending ... -
Experimental verification of boundary conditions for numerical simulation of airflow in a benchmark ventilation channel
(EDP Sciences, 2016-03-28)Correct definition of boundary conditions is crucial for the appropriate simulation of a flow. It is a common practice that simulation of sufficiently long upstream entrance section is performed instead of experimental ... -
High Quality Steel Casting by Using Advanced Mathematical Methods
(MDPI, 2018-12-04)The main concept of this paper is to utilize advanced numerical modelling techniques with self-regulation algorithm in order to reach optimal casting conditions for real-time casting control. Fully 3-D macro-solidification ... -
Influence of operating conditions and atomizer design on circumferential liquid distribution from small pressure-swirl atomizer
(EDP Sciences, 2017-05-12)The spray symmetry is an important aspect in most practical applications. However, it is often an overlooked parameter. A measurement of circumferential distribution was carried out by a circular-sectored vessel on several ... -
The influence of spill-line geometry on a spray generated by a pressure-swirl atomizer
(EDP Sciences, 2016-03-28)An experimental investigation of characteristics of spray generated by a pressure-swirl atomizer (spill-return type) was performed using shadowgraphy and Phase-Doppler Anemometry (PDA). Several different geometries of the ... -
Measurement of an electronic cigarette aerosol size distribution during a puff
(EDP SCIENCES, 2017-05-12)Electronic cigarettes (e-cigarettes) have become very popular recently because they are marketed as a healthier alternative to tobacco smoking and as a useful tool to smoking cessation. E-cigarettes use a heating element ... -
Optimal design of structure in rheological models: an automotive application to dampers with high viscosity silicone fluids
(JVE International, 2017-10-09)Dynamic torsional vibration dampers are for a long time inherent integral components of internal combustion engines. One of the most common types of the dynamic dampers is a silicone damper. It has been, for many years, ... -
Performance of Twin-Fluid Atomizers for Atomization of Viscous Solutions
(EDP Sciences, 2014-11-18)The article compares the performace of two twin-fluid atomizers with different desing and fluid mixing principles for atomiyation of viscous liquids. -
Prediction of localized aerosol deposition in a realistic replica of human airways using experimental data and numerical simulation
(EDP Sciences, 2016-11-15)The presence of aerosol deposition hot-spots in human airways presumably contributes to development of various diseases. The overall aerosol deposition in human lungs can be predicted with sufficient accuracy nowadays. ... -
