UCNS3D is an open-source computational solver for compressible flows on unstructured meshes. State-of-the-art high-order methods and their associated benefits can now be implemented industrial-scale CFD problems due to the flexibility highly-automated generation offered by We present governing equations of physical models employed in UCNS3D, numerical framework developed solution. The code has been designed so that extended other systems straightforward. are validated towards a series...
In this paper a relaxed formulation of the posteriori Multi-dimensional Optimal Order Detection (MOOD) limiting approach is introduced for weighted essentially non-oscillatory (WENO) finite volume schemes on unstructured meshes. The main goal to minimise computational footprint MOOD by employing WENO schemes—by virtue requiring smaller number cells reduce their order accuracy compared an unlimited scheme. key characteristic present that Numerical Admissible Detector (NAD) not uniquely...
In this paper the relaxed, high-order, Multidimensional Optimal Order Detection (MOOD) framework is extended to simulation of compressible multicomponent flows on unstructured meshes. The diffuse interface methods (DIM) paradigm used that employs a five-equation model. implementation performed in open-source high-order flow solver UCNS3D. CWENO spatial discretisation selected due its reduced computational footprint and improved non-oscillatory behaviour compared original WENO variant....
Considerable progress has been made in deuterium-tritium-layered implosion experiments on the OMEGA Laser System, bringing prospects for thermonuclear ignition direct-drive configurations with megajoule-class lasers closer to reality. Doing so required navigating balance between improved 1D performance and multidimensional stability. Using statistical modeling based over 350 cryogenic implosions identify various degradation mechanisms, combined simulations experimental techniques such as...
The Plasma Liner Experiment (PLX) at Los Alamos National Laboratory is studying plasma-jet driven magneto-inertial fusion (PJMIF), an innovative approach in which a magnetized target plasma compressed and heated by spherically imploding liner. We report on experimental efforts towards formation experiments using colliding jets, formed coaxial guns with applied field. In the collision of high-beta we observe aspects collisional collisionless dynamics during jet stagnation, informed Doppler...
