Fire-spotting generated fires. Part II: The role of flame geometry and slope
(2022)
This is the second part of a series of two papers concerning fire-spotting generated fires. While, in the first part, we focus on the impact of macro-scale factors on the growth of the burning area by considering the ...
On the merits of sparse surrogates for global sensitivity analysis of multi-scale nonlinear problems: Application to turbulence and fire-spotting model in wildland fire simulators
(2019-02)
Many nonlinear phenomena, whose numerical simulation is not straightforward, depend on a set of parameters in a way which is not easy to predict beforehand. Wildland fires in presence of strong winds fall into this category, ...
Fire-spotting generated fires. Part I: The role of atmospheric stability
(2019-02)
This is the first part of two papers concerning fire-spotting generated fires. In this part we deal with the impact of macroscale factors, such as the atmospheric stability, and in the second part we deal with mesoscale ...
RandomFront 2.3 A physical parametrisation of fire-spotting for operational fire spread models: Implementation in WRF-Sfire and response analysis with LSFire+
(2018-12)
Fire-spotting is often responsible for a dangerous flare up in the wildfire and causes secondary ignitions isolated from
the primary fire zone leading to perilous situations. The main aim of the present research to provide ...
Concurent multi-scale physical parametrization of fire-spotting: A study on the role of macro- and meso-scale characteristics of the system
(2018)
The strong impact of wildfires in terms of lives and homes lost and of damage to ecosystems, calls
for an urgent improvement in the risk management. The aim of the present research is the
improvement of these software ...
Wildfire propagation modelling
(2018)
Wildfires are a concrete problem with a strong impact on human life, property and the environment, because
they cause disruption and are an important source of pollutants. Climate change and ...
Wildland fire propagation modelling
(2017-12)
Wildfire propagation modelling is a challenging problem due to its complex
multi-scale multi-physics nature. This process can be described by a reaction-
diffusion equation based on the energy balance principle. Alternative ...
Wildland fire propagation modeling: fire-spotting parametrisation and energy balance
(2017-07-04)
Present research concerns the physical background of a wild-fire propagation model
based on the split of the front motion into two parts - drifting and fluctuating. The drifting part is solved by the level set method and ...
Numerical valuation of two-asset options under jump diffusion models using Gauss-Hermite quadrature
(2017-04-19)
In this work a finite difference approach together with a bivariate Gauss–Hermite quadrature technique is developed for partial integro-differential equations related to option pricing problems on two underlying asset ...
