The tangential drag of an axially oscillating cylinder
… and frequencies, and experimenta1 values of the tangential (friction) drag coefficient are obtained. The experimental values of the drag coefficient are compared with values predicted by the exact solution to the Navier-Stokes equations for a smooth cylinder in laminar flow. The experimental data …

Tangential Flow Filtration for the Purification of Lucentis
… protein. This group has been working on the tangential flow filtration (TFF) portion of the project, which will be utilized multiple times throughout the separation and purification process. The primary purpose of tangential flow filtration is to exchange buffer solution. Exchanging buffer …

Combined tangential-normal injection into a supersonic flow
A combination of tangential and normal air injection into a Mach 3 airflow was experimentally studied. A rearward facing slot producing tangential injection at a nominal Mach number 1.7 was operated at several different total pressures. An array of transverse tubes of height equal to the slot …

Estimation Of Tangential Momentum Accommodation Coefficient Using Molecular Dynamics Simulation
The Tangential Momentum Accommodation Coefficient (TMAC) is used to improve the accuracy of fluid flow calculations in the slip flow regime. Under such conditions (indicated by Knudsen number greater than 0.001), the continuum assumption that a fluid velocity at a solid surface is equal to the …

Configuration Complexes and Tangential and Infinitesimal versions of Polylogarithmic Complexes
… polylogarithmic complexes as well as a tangential complex to the famous Bloch-Suslin complex (in weight 2) and to Goncharov's ``motivic`` complex (in weight 3), respectively, as proposed by Cathelineau [5]. Our main result is a morphism of complexes between the Grassmannian complexes and …

An investigation of the effect of a tangential gas velocity on combustion instability.
… of swirl changed during the run. A first tangential high frequency mode of combustion instability was developed and a significant change in stability conditions was found when a vortex flow was generated within the combustion chamber. It was found that a swirl in one direction tended to …

Finite element analysis of combined fracture and delamination on coated substrate under normal and tangential loading
… is subjected to contact loading of normal and tangential loading, originated from contact pressure and sliding contact. In this thesis, aeroengine brittle material has been modelled to simulate coating failure under combined fracture and delamination failure. Hard brittle coatings modelled are …

Design and Evaluation of a Lean-Premixed Hydrogen Injector with Tangential Entry in a Sector Combustor
… a PT6-20 turboprop engine. Swirl generated by tangential entry was utilized as a means to enhance mixing and as a convenient means to stabilize the flame. A prototype was designed to prevent flashback and promote a high degree of mixing, as well as a test combustor to evaluate the performance …

Surface Strain Measurement for Non-Intrusive Internal Pressure Evaluation of a Cannon
… the feasibility and accuracy of relating tangential strain along the sidewall of a gun barrel to the drastic internal pressure rise created during combustion. A transient structural, numerical modal was created using ANSYS of a 155 mm gun barrel. The pressure gradient was derived using a …

Structure Based, Two-dimensional, Anisotropic, Transient Heat Conduction model for Wood
… of wood thermal conductivities in the radial and tangential directions were conducted with the geometric models built up from the macro- and micro-structure observations. Theoretically, thermal conductivity in the radial direction is about 1.5 to 2.5 times of the tangential direction for softwood …

Experimental determination of blade forces in a cross-flow turbine
… magnitude of the fluid forces on the blades. The tangential and radial forces and the torque were measured on a test blade. Because the runner was made of plexiglas, the flow and the effects of the incidence angle at various speeds were observed. The pattern of blade loading over a revolution was …

Development of a novel micropipette aspiration-based force sensing technique to measure single cell sliding friction
… biological scenarios the motion of cells is tangential to the surface of contact such as in extravasation of leucocytes, blood flow regulation, and cell migration. In these cases, adhesion molecules on the cells form bonds with the substrate upon contact and when the cells propagate, the …

Two alternative tangential bond conditions are proposed and comparison is made with certain exact solutions for torsion of embedded rods, to determine the best choice of tangential bond condition for use with the embedded cable problem. An asymptotic analysis gives …
