European 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

Modern vision for critical flow in an egg-shaped section
Water Science and Technology, 2021 The critical regime plays a primordial role in the study of gradually varying flows by classifying flow regimes and slopes. Through this work, a new approach is proposed to analyze critical flow regime in an egg-shaped channel.

Flow resistance in skimming flow: A critical review [PDF]
, 2020 During very large rainfall events, dams and weirs must be equipped with adequate flood release facilities for a safe dissipation of the kinetic energy of the flow. With stepped spillway design, it is essential to predict accurately the flow resistance associated with the steps.

Critical flow velocities in cohesive saline soils [PDF]
E3S Web of Conferences, 2021 The article discusses the issue of determining non-erosion velocities for cohesive saline soil at the bottom and slopes of canals. Based on the formulas of Ts.E. Mirtskhulava for the determination of non-eroding velocities of water flow in cohesive soils,

The critical 2d Stochastic Heat Flow
Inventiones mathematicae, 2023 AbstractWe consider directed polymers in random environment in the critical dimension $$d = 2$$ d = 2 , focusing on the intermediate disorder regime when the model undergoes a phase transition. We prove that, at criticality, the diffusively

An Investigation into Sub-Critical Choke Flow Performance in High Rate Gas Condensate Wells
Energies, 2019 There have been some correlations in the literature to predict the gas and liquid flow rate through wellhead chokes under subcritical flow conditions. The majority of these empirical correlations have been developed based on limited production data sets ...
