A slip model for rarefied gas flows at arbitrary Knudsen number [PDF]
, 2008 A slip model for wall bounded rarefied gas flows is derived from kinetic theory. A corresponding modified Reynolds lubrication equation is obtained from the slip velocity boundary conditions at walls for high Knudsen number gas flows. The slip model in a

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT The rate of a heterogeneous catalytic process may simultaneously be described by several rate equations. In this case, discrimination between the plausible kinetic models is required. An intrinsic kinetic model of a heterogeneous catalytic process may successively be discriminated by the transition from a reaction rate‐limited regime to an ...

Application of the Transition Probability Matrix Method to High Knudsen Number Flow Past a Micro‐Plate [PDF]
, 2003 In this work we present numerical results for the problem of ‘high’ (of order unity) Knudsen number gas flow past a micro‐airfoil, for low flow velocity.

Three‐dimensional digital analysis of musteloid masticatory muscle architecture
The Anatomical Record, EarlyView.Musteloids span an enormous breadth of dietary modes within a single superfamily. In this study, we utilize digital dissection techniques to reconstruct the internal 3D anatomy of muscles within the musteloid feeding apparatus, and explore how dietary specializations might alter the size, orientation, and curvature of fascicles therein.

Journal of Applied Fluid Mechanics, 2017 The standard lattice Boltzmann equation, LBE, is inadequate for simulating gas flows in nano scale flows with Knudsen numbers higher than 0.1. In the present study, rarefied gas flow in nano porous structures is simulated using the modified Lattice ...

Conceptualizing Corporate Political Activity for Sustainability Governance—The CPA Cube
Business Strategy and the Environment, EarlyView.ABSTRACT Sustainability transformations in the economy, and related public policy decisions, are highly contested, attracting business involvement. To better understand how business influence on government impacts the success or failure of sustainability governance efforts, this paper extends the literature on corporate political activity (CPA) by ...

On Navier slip and Reynolds transpiration numbers
Archives of Mechanics, 2018 In this paper, based on the original argumentation of Reynolds and Maxwell, with consideration of previous experiences of the authors in the nano- and micro-flows area, a general form of boundary forces, that consist of contributions from the friction ...

Micro-scale cavities in the slip - and transition - flow regimes [PDF]
, 2006 Differences between Navier-Stokes-Fourier (NSF) slip/jump solutions and direct simulation Monte-Carlo (DSMC) computations are highlighted for a micro lid-driven cavity problem. The results indicate a need for better modelling techniques which at the same

Chemie Ingenieur Technik, EarlyView.Thermal defrosting limits desublimator efficiency in freeze‐drying. This review and case study compares thermal versus mechanical regeneration, links frost properties and external heat transfer to energy demand, and summarizes pilot‐scale scraping results enabling single‐unit, continuous lyophilization.

Release of multicomponent pheromones from porous fibres
The Canadian Journal of Chemical Engineering, EarlyView.Abstract Surface engineering empowers a polymer exclusion net to serve dual functions: physical exclusion and pheromonal release, allowing for pest control in agricultural crops. In previous work, a net woven from porous fibres releasing simple, single‐component alarm pheromones showed promising results in field tests.
