This concerns both natural organs or organ systems as well as devices that take over organ functions, such as the dialyzer. In these systems, it is usually difficult to visualize the internal distribution of the substances of interest in three dimensions or to recapitulate processes.  Virtual methods, such as flow simulation, often offer the only possibility of understanding internal system processes and interrelationships. They are therefore an ideal starting point for effective optimization of artificial organs, for example.<\/p>\n\n<figure class=\"wp-block-gallery has-nested-images columns-default is-cropped wp-block-gallery-1 is-layout-flex wp-block-gallery-is-layout-flex\">\n<figure class=\"wp-block-image size-large\"><img fetchpriority=\"high\" decoding=\"async\" width=\"522\" height=\"480\" data-id=\"3376\" src=\"https:\/\/www.asd-online.com\/wp-content\/uploads\/2022\/02\/reinraum_aerosol.jpg\" alt=\"\" class=\"wp-image-3376\" srcset=\"https:\/\/www.asd-online.com\/wp-content\/uploads\/2022\/02\/reinraum_aerosol.jpg 522w, https:\/\/www.asd-online.com\/wp-content\/uploads\/2022\/02\/reinraum_aerosol-300x276.jpg 300w\" sizes=\"(max-width: 522px) 100vw, 522px\" \/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"336\" height=\"443\" data-id=\"3378\" src=\"https:\/\/www.asd-online.com\/wp-content\/uploads\/2022\/02\/Dosiergeraet_Geschwindigkeit.jpg\" alt=\"\" class=\"wp-image-3378\" srcset=\"https:\/\/www.asd-online.com\/wp-content\/uploads\/2022\/02\/Dosiergeraet_Geschwindigkeit.jpg 336w, https:\/\/www.asd-online.com\/wp-content\/uploads\/2022\/02\/Dosiergeraet_Geschwindigkeit-228x300.jpg 228w\" sizes=\"(max-width: 336px) 100vw, 336px\" \/><\/figure>\n<figcaption class=\"blocks-gallery-caption wp-element-caption\">Simulation of the recovery test: Green isosurfaces of particle concentration equal to 1\/100 of the initial concentration after 100s \/ velocity distribution in a metered dose inhaler<\/figcaption><\/figure>\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Mass transfer and mass transport are associated with processes such as diffusion and convection, adsorption and separation as well as mass transfer and mass transfer (e.g. through porous media).
