Fire and Materials, EarlyView.ABSTRACT The need for numerical‐based approaches to investigate the fire behaviour in buildings with combustible components is growing due to the increasing use of timber by the construction industry to meet the ‘Climate Action Plan 2050’. This requires consideration of the complex kinetic processes that take place during the burning of the wood in the

Investigation on gas generation characteristics in transformer oil under vibration
IET Generation, Transmission &Distribution, Volume 16, Issue 24, Page 5026-5040, December 2022., 2022 Abstract Operating experience has shown that characteristic gases can be found in oil‐immersed power transformers and high‐voltage reactors under strong vibration without discharge or thermal faults occurring. This will cause misdiagnosis of Dissolved Gases Analysis (DGA).

A Relaxation Scheme for the Simulation of Low Mach Number Flows [PDF]
, 2017 A scheme for the simulation of inviscid flows with low Mach number is derived. The scheme is built on a relaxation system and it is based on a linear implicit time discretization. The advective part is discretized by a convex combination of upwind and centered schemes, in order to recover the correct limit when the Mach number goes to zero.

Electronic Journal of Differential Equations, 2019 In this article, we consider the low Mach number limit of the compressible nematic liquid crystal flows in a 3D bounded domain. We establish the uniform estimates with respect to the Mach number for the strong solutions with large initial data in a ...

Continuous Adjoint to Proudman's Formula for Aeroacoustic Shape Optimization
International Journal for Numerical Methods in Fluids, EarlyView.This paper presents a cost‐efficient framework for aeroacoustic shape optimization by developing the adjoint to Proudman's formula, coupled with the steady‐state RANS equations and the k‐ ω$$ \omega $$ SST turbulence model. The aeroacoustic model and the adjoint solver are initially validated/verified with experimental data/finite differences, before ...
