The scientific journal Physics of Fluids will host a study by UvA computer scientist Gábor Závodszky on the cover of its May issue. The article describes a new model for the flow of red blood cells in the blood.

Blood is a special substance that is extremely good in transporting all kinds of substances through the body. About half of our blood consists of red blood cells. These red blood cells are fairly ‘soft’ and easily deformable. During the flow of the blood, the blood cells constantly collide with each other and with other obstacles. They can also sometimes accumulate. In order to be able to make a good model of blood, it is necessary to include collisions and the deformability of red blood cells.

Until now, this has often not been sufficiently taken into account in models. Závodszky and his colleagues from the UvA Institute for Informatics have expanded an existing model with the deformability of the red blood cells. This is important, because a more precise model helps doctors to better predict the behavior of the blood in all sorts of diseases.

The article in which the team describes their model was published online on 12 March at Physics of Fluids. It will adorn the cover of this same scientific journal on 1 May.
