Para2Mesh: A dual diffusion framework for moving mesh adaptation

A new dual diffusion framework, Para2Mesh, has been proposed to achieve direct prediction from design parameters to adaptive meshes aligned with the flow field. This approach overcomes the limitation of previous methods requiring posteriori solution information, enabling more efficient and accurate computational fluid dynamics simulati...

Breakthrough rotor model enables safe transitions for aerial-aquatic vehicles

A research team developed an advanced adaptive aerodynamic model inspired by finite vortex theory to predict rotor performance in complex two-phase flow environments. The Finite Vortex Rotor Model (FVRM) incorporates water surface deformation and accounts for the complex feedback between rotor downwash and liquid response.

How do different types of jets control dynamic stall?

A study published in Chinese Journal of Aeronautics reveals that DSJ combines the stability of steady jets and efficiency of pulsed jets, providing better control effects under similar momentum coefficients. The unique quasi-steady characteristics of DSJ avoid large fluctuations in real-time aerodynamics.

One in four chance per year that rocket junk will enter busy airspace

A recent UBC study found that there's a 26% annual chance of space rocket junk re-entering the atmosphere and passing through a busy flight area, highlighting the potential for uncontrolled debris to disrupt flights. The researchers emphasize the need for policymakers to take action to address this issue.

The roar and crackle of Artemis 1

Researchers measured noise levels at locations around the launch pad, finding maximum sound levels exceeded predicted values by nearly 20 decibels. The study's findings will help validate and improve existing noise prediction models to protect equipment and surrounding environments.

Saturn V was loud but didn't melt concrete

Researchers used physics-based models and historical data to debunk internet claims about the Saturn V's acoustic power, finding levels of 203 decibels, comparable to commercial jet engines. The study also predicts sound levels for NASA's SLS Artemis 1 launch and provides educational tools for college-level physics classrooms.

Tiny probes could sail to outer planets with the help of low-power lasers

Researchers calculate that low-power lasers on Earth could launch and maneuver small probes equipped with silicon or boron nitride sails, propelling them to much faster speeds than rocket engines. The lasers could propel tiny sailed probes on interplanetary or interstellar missions without requiring large amounts of fuel.
