ABSTRACT We study the role of thermal conduction in laser‐produced tin plasma sources of extreme ultraviolet (EUV) light using radiation‐hydrodynamic simulations. Adopting the flux‐limited Spitzer–Härm approach, we investigate the sensitivity of the electron temperature, electron density, net in‐band emissivity, and conversion efficiency to the choice ...

The graphical abstract depicts the workflow for porous‐ and fractured‐media simulations, where stochastically generated discrete natural fractures are required for the fracture‐media simulation. Abstract CO 2 ${\text{CO}}_{2}$ leakage is one of the main risks and barriers to geologic carbon storage. However, under the high‐temperature and high‐pressure

This study establishes a multi‐factor coupling framework for predicting breakdown pressure in laminated shale by integrating experimental hydraulic fracturing tests, physics‐informed neural networks (PINNs), and Sobol sensitivity analysis. It reveals how differential stress, the bedding dip angle, and the injection rate interact to influence fracture ...

Modeling proppant transport and settling in a 3D propagating fracture
A versatile multiphysics tool is presented for simulating the complex processes involved in hydraulic fracturing treatments. The model couples fracture opening and propagation, variable‐density slurry flow, and proppant particle transport within the multiphysics object‐oriented simulation environment framework, based on two‐phase mixture equations and ...

On supersymmetric Dirac delta interactions [PDF]
[EN] In this paper we construct N = 2 supersymmetric (SUSY) quantum mechanics over several configurations of Dirac- δ potentials from one single delta to a Dirac “comb ”.

Energía de Casimir en sistemas definidos con potencial delta de Dirac
La energía de vacío es uno de los fenómenos que da lugar a fluctuaciones cuánticas de campos. El objetivo de este trabajo es calcular el efecto Casimir, fenómeno producido por la interacción de las fluctuaciones cuánticas con los cuerpos de un sistema.Por un lado, veremos el caso de dos placas paralelas tanto neutras como perfectamente conductoras, las
