Turbulence of a Unidirectional Flow
Recent advances in the theory of turbulent solutions of the Navier-Stokes equations are discussed and the existence of their associated invariant measures. The statistical theory given by the invariant measures is described and associated with historically-known scaling laws. These are Hack’s law in one dimension, the Bachelor-Kraichnan law in two dimensions and the Kolmogorov’s scaling law in ...
متن کاملEvidence for unidirectional flow through plasmodesmata.
The leaf trichome of tobacco (Nicotiana tabacum) represents a unique secretory structure in which the basal trichome cell is connected to the epidermis by numerous plasmodesmata (PD). Small fluorescent probes microinjected into the basal trichome cell moved apically into distal trichome cells but not into the subtending epidermal cell. In marked contrast, the same probes moved apically into tri...
متن کاملPolca simulation of a unidirectional flow system
Polca is a material control system that focuses on shop floor throughput time control in production situations with high variety and customization. It uses an authorization mechanism that consists of route-specific capacity signals (polca cards) and product-specific release signals (ERP system). The route-specific capacity signals level the maximum amount of work in progress within a loop. Each...
متن کاملAutomatic non-rebreathing valve.
EFFICIENT ventilation of the anaesthetized patient, without carbon dioxide absorption, can be carried out using the valve to be described. It is simple, reliable, efficient and silent. In figure 1 A and E are low resistance valves. P, and P2 form a bypass opening into the balloon B, which lies free in the exit tube X. The balloon is made of very thin rubber and is of such a size that when infla...
متن کاملInvestigation of the Flow and Cavitation in a Butterfly Valve
Since knowledge on hydrodynamic torque of a butterfly valve is very important for butterfly valve design, its hydrodynamic torque is investigated in this paper. In reality, the investigation of the loss coefficient and torque from some experiments will take a long time and a lot of money. This paper presents a statistical study of the flow past the butterfly valve in a static analysis using com...
