🔩 "Engineering is the art and science of nuts and bolts.” – Haresh Sippy
Hey friends & nerds! 👋
Welcome to a new episode of the Sunday Science Newsletter where we explore science, systems & tools that help us become smarter scientists.
🎙️Fluid Dynamics, Computer Graphics & Winning Oscars – Jos Stam
💦 Exploring the Venturi Effect
When flowing through a constricted area of a pipe, a fluid’s velocity increases and its static pressure decreases. This principle is known as the Venturi effect. Comsol explains this effect, including some of its applications.
💨 Aircraft Vortex Generators – The Nacelle Strakes
In modern transport aircraft, underwing engine nacelle installation is the most common design choice. Here, the engine nacelles which are tightly coupled with the wing have a huge impact on the maximum lift and stall angle of the wing. With the usage of larger by-pass ratio engines over the years, the adverse effects of the nacelle on the wing’s performance have increased dramatically, especially so when the high lift devices are deployed.
💻 What is Meshing? | An OnScale Blog
In FEM, we create a mesh which splits the domain into a discrete number of elements for which the solution can be calculated. The data is then interpolated across the whole domain.

💻 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
The Finite Volume Method in Computational Fluid Dynamics
This textbook explores both the theoretical foundation of the Finite Volume Method (FVM) and its applications in Computational Fluid Dynamics (CFD). Readers will discover a thorough explanation of the FVM numerics and algorithms used for the simulation of incompressible and compressible fluid flows, along with a detailed examination of the components needed for the development of a collocated unstructured pressure-based CFD solver. Two particular CFD codes are explored. The first is uFVM, a three-dimensional unstructured pressure-based finite volume academic CFD code, implemented within Matlab. The second is OpenFOAM®, an open source framework used in the development of a range of CFD programs for the simulation of industrial scale flow problems.
With over 220 figures, numerous examples and more than one hundred exercise on FVM numerics, programming, and applications, this textbook is suitable for use in an introductory course on the FVM, in an advanced course on numerics, and as a reference for CFD programmers and researchers.-
