Abstract The manufacturing of exhaust filter systems for cars typically comprises the forming a tube and later stuffing formed product with ceramic monolith an elastomer mat filtration. It is shown, that oval tubes process leads to inhomogeneous deformation final wherefore it must be considered when designing tools step. high number iterations tool design can hence reduced. Additionally, under ...

We study the flow of an incompressible viscous Newtonian fluid through a tube with compliant walls. The tube is assumed to be straight, long, with circular cross–sections of variable radius. Elastic properties of the tube wall are described by the linear membrane shell equations. The flow is driven by the pulsatile inlet and outlet dynamic pressure data. Applying asymptotic techniques we derive...
