Numerical Quenching for Heat Equations with Coupled Nonlinear Boundary Flux [PDF]

open access: yesInternational Journal of Analysis and Applications, 2019
In this paper, we study a numerical approximation of the following problem ut = uxx, vt = vxx, 0 < x < 1, 0 < t < T; ux(0, t) = u−m(0, t) + v−p(0, t), vx(0, t) = u−q (0, t) + v−n(0, t) and ux(1, t) = vx(1, t) = 0, 0 < t < T, where m, p,

Numerical Study of Quenching Distances for Side-Wall Quenching Using Detailed Diffusion and Chemistry [PDF]

open access: yes, 2021
The numerical investigation of quenching distances in laminar flows is mainly concerned with two setups: head-on quenching (HOQ) and side-wall quenching (SWQ).

Proper generalized decomposition of time-multiscale models [PDF]

open access: yes, 2011
Models encountered in computational mechanics could involve many time scales. When these time scales cannot be separated, one must solve the evolution model in the entire time interval by using the finest time step that the model implies.

Modelling fluorescence quenching in systems with restricted diffusion: applications to oligonucleotides and polypeptides [PDF]

open access: yes, 2004
The objectives of the present thesis are 1) to systematically develop a series of models and theoretical expressions for the diffusion-controlled reaction, which can be used to analyze the time-resolved fluorescence data in systems where the diffusion is

Direct numerical simulation of turbulence at lower costs [PDF]

open access: yes, 1995
Direct Numerical Simulation (DNS) is the most accurate, but also the most expensive, way of computing turbulent flow. To cut the costs of DNS we consider a family of second-order, explicit one-leg time-integration methods and look for the method with the

Study of Tailored Hot Stamping Process on Advanced High-Strength Steels

open access: yesJournal of Manufacturing and Materials Processing, 2022
Ultra-high-strength steels (UHSS) combined with tailor-stamping technologies are increasingly being adopted in automotive body production due to crashworthiness improvements and part weight reduction, which meet safety and energy saving demands. Recently,

Heat transfer analysis of the forced air quenching with non-isothermal and non-uniform oxidation.

open access: yesPLoS ONE, 2021
In this paper, the heat transfer characteristics of the forced air quenching with non-isothermal and non-uniform oxidation are investigated. By introducing the variations of interfacial temperature and oxygen partial pressure, a three-layered non ...

Theoretical and numerical study of the combustion properties of premixed hydrogen/natural gas/air at a sub-atmospheric pressure of 0.849 Bar

open access: yesCT&F Ciencia, Tecnología & Futuro, 2021
Due to the energy transition worldwide, renewable energy sources complementary to fossil fuels are being sought. Considering that hydrogen generates only water when reacting with air, the application of hydrogen can play a leading and complementary role ...

Medium-induced cascade in expanding media

open access: yesJournal of High Energy Physics, 2020
Detailed insight into the interplay between parton energy loss and the way deconfined medium created in heavy-ion collisions expands is of great importance for improving the understanding of the jet quenching phenomenon. In this paper we study the impact
