Critical Flow – Towards a Construction Flow Theory [PDF]

open access: yes, 2006
This paper introduces the concept of Construction Physics as a more comprehensive way of understanding the construction process from a flow perspective. It establishes a preliminary definition of the term and investigates briefly the present knowledge, flow models and methods for their management.

Critical Flow Restricting Orifices [PDF]

open access: green, 1988
The installation of flow restricting orifices in both the nitrogen gas and instrument air supply lines in the D-Zero Building limits the flow available to the various users. These orifices are strategically positioned along the lines such that no one user can monopolize the gas supply and deprive others of their flow required to operate.

On the place of sonic points in a critical flow [PDF]

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2021
Stationary irrotational barotropic gas flows are investigated on the basis of the analysis of three-dimensional Euler equations. Critical flows in the article are those in which the Mach number is everywhere less than or equal to one, and at least at one

A computational approach for shallow water forced Korteweg–De Vries equation on critical flow over a hole with three fractional operators

open access: yesAn International Journal of Optimization and Control: Theories & Applications (IJOCTA), 2021
The Korteweg–De Vries (KdV) equation has always provided a venue to study and generalizes diverse physical phenomena. The pivotal aim of the study is to analyze the behaviors of forced KdV equation describing the free surface critical flow over a hole by

Comparative Analysis of Supersonic Flow in Atmospheric and Low Pressure in the Region of Shock Waves Creation for Electron Microscopy

open access: yesSensors, 2023
This paper presents mathematical-physics analyses in the field of the influence of inserted sensors on the supersonic flow behind the nozzle. It evaluates differences in the flow in the area of atmospheric pressure and low pressure on the boundary of ...

On 3-flow-critical graphs

open access: yesEuropean Journal of Combinatorics, 2022
A bridgeless graph $G$ is called $3$-flow-critical if it does not admit a nowhere-zero $3$-flow, but $G/e$ has for any $e\in E(G)$. Tutte's $3$-flow conjecture can be equivalently stated as that every $3$-flow-critical graph contains a vertex of degree three. In this paper, we study the structure and extreme edge density of $3$-flow-critical graphs. We
