Skeletal Reaction Models for Gasoline Surrogate Combustion

Yinmin Liu, Hessam Babaee, Peyman Givi +2

Skeletal reaction models are derived for a four-component gasoline surrogate model via an instantaneous local sensitivity analysis technique. The sensitivities of the species mass…

Reduced Order Modeling of Turbulence-Chemistry Interactions using Dynamically Bi-Orthonormal Decomposition

Aidyn Aitzhan, Arash G. Nouri, Peyman Givi +1

The performance of the dynamically bi-orthogonal (DBO) decomposition for the reduced order modeling of turbulence-chemistry interactions is assessed. DBO is an on-the-fly low-rank…

PeleLM-FDF Large Eddy Simulator of Turbulent Combustion

Aidyn Aitzhan, Shervin Sammak, Peyman Givi +1

A new computational methodology, termed "PeleLM-FDF" is developed and utilized for high fidelity large eddy simulation (LES) of complex turbulent combustion systems. This methodolo…

Skeletal Reaction Models for Methane Combustion

Yinmin Liu, Hessam Babaee, Peyman Givi +3

A local-sensitivity-analysis technique is employed to generate new skeletal reaction models for methane combustion from the foundational fuel chemistry model (FFCM-1). The sensitiv…

Skeletal Model Reduction with Forced Optimally Time Dependent Modes

A. G. Nouri, H. Babaee, P. Givi +2

Sensitivity analysis with forced optimally time dependent (f-OTD) modes is introduced and its application for skeletal model reduction is demonstrated. f-OTD expands the sensitivit…

On-the-fly Reduced Order Modeling of Passive and Reactive Species via Time-Dependent Manifolds

Donya Ramezanian, Arash G. Nouri, Hessam Babaee

One of the principal barriers in developing accurate and tractable predictive models in turbulent flows with a large number of species is to track every species by solving a separa…

Rectilinear Shortest Paths Among Transient Obstacles

Anil Maheshwari, Arash Nouri, Jörg-Rüdiger Sack

This paper presents an optimal algorithm for determining time-minimal rectilinear paths among transient rectilinear obstacles. An obstacle is transient if it exis…

Time-Dependent Shortest Path Queries Among Growing Discs

Anil Maheshwari, Arash Nouri, Jörg-Rüdiger Sack

The determination of time-dependent collision-free shortest paths has received a fair amount of attention. Here, we study the problem of computing a time-dependent shortest path am…

Query Shortest Paths Amidst Growing Discs

Arash Nouri, Jorg-Rudiger Sack

The determination of collision-free shortest paths among growing discs has previously been studied for discs with fixed growing rates. Here, we study a more general case of this pr…
