Interpolation of gas-liquid multicomponent fluid properties for piping fluid flow analysis [PDF]
E3S Web of Conferences, 2023 The article proposes the use of bicubic spline interpolation to optimize hydraulic and thermal calculations while processing thermodynamic library data. Research was carried out both in single-phase gas and liquid regions, as well as in the two-phase gas-

A method of analysis of complex hydraulic networks [PDF]
E3S Web of Conferences, 2020 A simple and reliable iterative solution method of classical hydraulic network flow rate distribution problem is described. The method is based on chord linearization of inverse branch loss function which keeps basic branch properties.

Modernization of Todini Global Gradient Algorithm for hydraulic analysis of networks with choked flow [PDF]
E3S Web of Conferences, 2020 The modification of well-known Global Gradient Algorithm for hydraulic network flow distribution problem is proposed. This modification is based on problem equations rewritten in “upstream” form and on modified form of linearization, and can be ...

The Canonical Bijection Between Pipe Dreams and Bumpless Pipe Dreams [PDF]
International Mathematics Research Notices 2023, 2021 We present a direct bijection between reduced pipe dreams and reduced bumpless pipe dreams by interpreting reduced compatible sequences on bumpless pipe dreams and show that this bijection preserves Monk's formula, establishing its canonical nature.

LOSS OF WATER IN PUBLIC BUILDINGS (ON THE EXAMPLE OF MGSU) [PDF]
Stroitel’stvo: Nauka i Obrazovanie, 2016 Any public building is a consumer of water resources. A huge amount of clean drinking water is used for various needs especially in buildings where there are a large number of people, for example, institutions of higher education. It should be noted that

A pipe dream perspective on totally symmetric self-complementary plane partitions [PDF]
Forum of Mathematics, Sigma. 2024;12:e17, 2023 We characterize totally symmetric self-complementary plane partitions (TSSCPP) as bounded compatible sequences satisfying a Yamanouchi-like condition. As such, they are in bijection with certain pipe dreams. Using this characterization and the recent bijection of [Gao-Huang] between reduced pipe dreams and reduced bumpless pipe dreams, we give a ...
