Simulation of Airway Deposition of an Aerosol Drug in COPD Patients
Medical aerosols are key elements of current chronic obstructive pulmonary disease (COPD) therapy. Therapeutic effects are conditioned by the delivery of the right amount of medication to the right place within the airways, ...
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 ...
A parametric study of influence of material properties on car cabin environment
(EDP Sciences, 2014-03-25)
Recently the author presented the paper describing a car cabin heat load model for the prediction of the car cabin environment. The model allowed to simulate a transient behavior of the car cabin, i.e. radiant ...
Effect of nanoparticles concentration on the characteristics of nanofluid sprays for cooling applications
This study addresses the effect of nanofluid synthesis on the rheological properties of the resulting fluid and their consequent effect on the characteristics (size and velocity distribution of droplets, spray cone angle, ...
Seasonal COP of an Air-to-Water Heat Pump when Using Predictive Control Preferring Power Production from Renewable Sources in the Czech Republic
The paper presents a parametric study evaluating the effects of various predictive controls on the operating parameters of heat pumps. The heat pump represents a significant power appliance in the residential sector. Its ...
Selection of model liquid with refractive index matching for visualization of internal flow in a scaled atomizer model
(EDP Sciences, 2019-06-28)
A scaled transparent modular model of pressure-swirl (PS) atomizer was prepared from cast PMMA (Poly(methyl methacrylate), Perspex™, Plexiglas™) with the aim to achieve a better understanding of internal flow and subsequent ...
2D and 3D numerical modelling of internal flow of Pressure-swirl atomizer
(EDP Sciences, 2019-06-28)
This paper compares 2D axisymmetric and 3D numerical models used to predict the internal flow of a pressure-swirl atomizer using a commercial software Ansys Fluent 18.1. The computed results are compared with experimental ...
Investigation of the velocity field downstream of a benchmark vent using numerical simulation and hot-wire anemometry
(EDP Sciences, 2018-11-14)
The velocity field in the area behind the automotive vent was measured by hot-wire anenemometry in detail and intensity of turbulence was calculated. Numerical simulation of the same flow field was performed using Computational ...
Investigation of pressure swirl sprays using Volumetric PIV
The volumetric measurement technique (V3V-Flex©) was used to investigate the spray generated by two pressure swirl atomizers (PSAs). Both a simplex pressure swirl atomizer and a spill-return pressure swirl atomizer were ...
