    Pressure-robustness in quasi-optimal a priori estimates for the Stokes problem. ETNA - Electronic Transactions on Numerical Analysis

    No full text
    Recent analysis of the divergenceconstraint in the incompressible Stokes/Navier-Stokes problemhas stressed the importanceof equivalence classes of forces and how they play a fundamental rolefor an accurate space discretization. Two forces in the momentum balance arevelocity-equivalent if they lead to the same velocity solution,i.e., if and only if the forces differ by only a gradient field.Pressure-robust space discretizations are designed torespect these equivalence classes.One way to achieve pressure-robust schemesis to introduce a non-standard discretization of the right-hand sideforcing term for any inf-sup stable mixed finite element method.This modification leads to pressure-robust and optimal-orderdiscretizations, buta proof was only available for smooth situations and remained open in the case of minimal regularity, where it cannot beassumed that the vector Laplacian of the velocity is at leastsquare-integrable. This contribution closes this gap bydelivering a general estimate for the consistency error thatdepends only on the regularity of the data term.Pressure-robustness of the estimate is achieved by the fact thatthe new estimate only depends on the L2L^2-norm of theHelmholtz-Hodge projector of the data termand not on the L2L^2-norm of the entire data term. Numerical examples illustrate the theory

    Emergierende Technowissenschaften (ITA-manu:script 20-01)

    No full text
    Systembiologie und Synthetische Biologie können als Beispiele emergierender Technowissenschaft verstanden werden. Sie sind wesentlich geprägt durch Zukunftsversprechungen und Visionen, eine bestimmte Logik der Namensgebung und -verwendung, bestimmte Formen sozialer Organisation, die Einbettung in ein bestimmtes Förder- und Innovationsregime sowie eine charakteristische Matrix an Handlungsorientierungen in der Forschungspraxis. Diese spezifische Konstitution von Forschung hat ihrerseits Konsequenzen für Wissenschaftsforschung, Wissenschaft und Wissenschaftspolitik
