Validation of a two-fluid turbulence model in comsol multiphysics for the problem of flow around aerodynamic profiles.

The article presents a study of a two-fluid turbulence model in the Comsol Multiphysics software package for the problem of a subsonic flow around the DSMA661 and NACA 4412 airfoils with angles of attack of 0 and 13.87 degrees, respectively. In this paper, the finite element method is used for the numerical implementation of the turbulence equations.

[Secretory cycle of pancreatic acinar cells in different functional states].

Time parameter and secretory cycle in acinar cells of the pancreas were studied after atropine, trazilol, pilocarpine administration, and subtotal resection of the small intestine. The duration of secretory cycle was found to be about 45 min. in intact rats.
