💨 Turbulence breaks a tree’s branches, but only tickles an eagle’s wings.
Hey friends & nerds! Welcome to the Sunday Science Newsletter – in this newsletter we explore & discuss strategies, systems & tools that help us become better, smarter and more effective scientists, gadgeteers and thinkers.

💧Turbulence Modeling Resource from NASA
The purpose of this site is to provide a central location where Reynolds-averaged Navier-Stokes (RANS) turbulence models are documented. This effort is guided by the Turbulence Model Benchmarking Working Group (TMBWG), a working group of the Fluid Dynamics Technical Committee of the American Institute of Aeronautics and Astronautics (AIAA).
💻 AI has cracked a key mathematical puzzle for understanding our world
Partial differential equations can describe everything from planetary motion to plate tectonics, but they’re notoriously hard to solve.
🌊 Strategies for turbulence modelling and simulations (P.R.Spalart)
This is an attempt to clarify and size up the many levels possible for the numerical prediction of a turbulent flow, the target being a complete airplane, turbine, or car.
💻 Engineering Tool of the Week – Sparselizard
Sparselizard is a high-performance, multiphysics, hp-adaptive, open source C++ finite element library running on Linux, Mac and Windows. A fast algorithm for mesh-to-mesh interpolation and a general implementation of the mortar finite element method allow to easily work with non-matching meshes and provide general periodic conditions. FEM simulations can be weakly or strongly coupled to lumped electric circuits.
Sparselizard can handle a general set of problems in 3D, 2D axisymmetric, 2D and 1D such as mechanical (anisotropic elasticity, geometric nonlinearity, buckling, contact, crystal orientation), fluid flow (laminar, creeping, incompressible, compressible), stabilized advection-diffusion, nonlinear acoustic, thermal, thermoacoustic, fluid-structure interaction, electric, magnetic, electromagnetic, piezoelectric, superconductor,... problems with a transient, (multi)harmonic or damped/undamped eigenmode analysis.
📚 Book of the Week
A First Course in the Finite Element Method, Enhanced Edition
This unique book is written so you can easily comprehend content without the usual prerequisites, such as structural analysis. This book is ideal, whether you are a civil or mechanical engineering student primarily interested in stress analysis and heat transfer, or you need a foundation for applying FEM as a tool in solving practical physical problems.
New and expanded real-world examples and problems demonstrate FEM applications in a variety of engineering and mathematical physics-related fields. Each chapter uses a consistent structure with step-by-step, worked-out examples, ideal for undergraduate or graduate-level study. A new WebAssign digital platform provides additional online resources to clarify concepts and assist you in completing assignments.
