Impact of H2/CH4 blends on the flexibility of micromix burners applied to industrial combustion systems 

Lopez-Ruiz, G.; Alava, I.; Blanco, J. M. (2023-05-01)
The present paper investigates the feasibility of using H2/CH4 fuel blends in micromix-type burners applied to industrial combustion systems. The micromix burner concept, characterised by the formation of miniaturised and ...

Generalized plane offsets and rational parameterizations 

Rochera, D.Autoridad BCAM (2023-04-21)
In the first part of the paper a planar generalization of offset curves is introduced and some properties are derived. In particular, it is seen that these curves exhibit good regularity properties and a study on ...

Tribological variable-friction coefficient models for the simulation of dense suspensions of rough polydisperse particles 

Ruiz-Lopez, J.A.; Prasanna Kumar, S. S.; Vazquez-Quesada, A.; De Vicente, J.; Ellero, M.Autoridad BCAM (2023-03-01)
The rheology of concentrated suspensions of particles is complex and typically exhibits a shear-thickening behavior in the case of repulsive interactions. Despite the recent interest arisen, the causes of the shear-thickening ...

A Deep Double Ritz Method (D2RM) for solving Partial Differential Equations using Neural Networks 

Uriarte, C.Autoridad BCAM; Pardo, D.Autoridad BCAM; Muga, I.; Muñoz-Matute, J.Autoridad BCAM (2023-02-15)
Residual minimization is a widely used technique for solving Partial Differential Equations in variational form. It minimizes the dual norm of the residual, which naturally yields a saddle-point (min–max) problem over the ...

An explicit characterization of isochordal-viewed multihedgehogs with circular isoptics 

Rochera, D.Autoridad BCAM (2023-02-10)
A curve α is called (ϕ, ℓ)-isochordal viewed if a straight segment of constant length ℓ can slide with its endpoints on α and such that their tangents to α at these endpoints make a constant angle ϕ. These tangents determine ...

Exploiting Kronecker structure in exponential integrators: Fast approximation of the action of  phi-functions of matrices via quadrature 

Croci, M.; Muñoz-Matute, J.Autoridad BCAM (2023-02-04)
In this article, we propose an algorithm for approximating the action of  $\varphi$-functions of matrices against vectors, which is a key operation in exponential time integrators. In particular, we consider matrices with ...

Limited Visual Range in the Social Force Model: Effects on Macroscopic and Microscopic Dynamics 

García, A.Autoridad BCAM; Hernández-Delfin, D.; Lee, D.-J.Autoridad BCAM; Ellero, M.Autoridad BCAM (2023-01-15)
The Social Force Model has been widely used to simulate pedestrian dynamics. Its simplicity and ability to reproduce some collective patterns of behavior make it an adequate tool in the field of pedestrian dynamics. However, ...

Non-affine motion and selection of slip coefficient in constitutive modeling of polymeric solutions using a mixed derivative 

Nieto, D.Autoridad BCAM; Español, P.; Ellero, M.Autoridad BCAM (2023-01-01)
Constitutive models for the dynamics of polymer solutions traditionally rely on closure relations for the extra stress or related microstructural variables (e.g., conformation tensor) linking them to flow history. In this ...

Screw rotor manufacturing via 5-axis flank CNC machining using conical tools 

Bizzarri, M.; Bo, P.; Barton, M.Autoridad BCAM (2022-12)
We propose a new method for 5-axis flank computer numerically controlled (CNC) machining of screw rotors using conical tools. The flanks of screw rotors consist of helical surfaces, which predetermines the motion of the ...

Combining DPG in space with DPG time-marching scheme for the transient advection–reaction equation 

Muñoz-Matute, J.Autoridad BCAM; Demkowicz, L.; Roberts, N. V. (2022-12-01)
In this article, we present a general methodology to combine the Discontinuous Petrov-Galerkin (DPG) method in space and time in the context of methods of lines for transient advection-reaction problems. We  rst introduce ...
