Computational Fluid Dynamics group

Thank you @UConnEngineer students for being amazing during this difficult semester!

📣 We are recruiting for fully funded PhD positions in fluid dynamics, with applications in naval and aerospace engineering. We are looking for motivated students interested in turbulence, computational fluid dynamics, high-performance computing, and complex flow physics. Please consider applying if you are eligible and interested, and please RT/share.

Please join us tomorrow (March 17) at the #APSSummit25 for our talk on clouds and turbulence in the atmosphere. Session MAR-B45 in 263A at 11:42 am. Most of our talk is for non-experts in the field: we will review some of the fundamentals, provide historical perspective and context, and discuss some of our latest work on cloud organization. We have lots of nice visuals too! Our topic is: Turbulence and clouds in the atmosphere: From the last unresolved classical physics problem to the largest uncertainty in climate projections Abstract: Clouds play a key role in the Earth's energy balance. Small changes in low-cloud area cover have a comparable magnitude on the global energy budget as that of the anthropogenic emissions of greenhouse gases. Clouds are interconnected with atmospheric turbulence because turbulent transport causes the variations of temperature and humidity that lead to cloud formation. In recent years, the growth of computing power combined with advances in atmospheric physics modeling have yielded high-fidelity simulations establishing numerical simulation as a major tool for cloud physics discovery. Focusing on high-resolution simulation of atmospheric boundary-layer clouds, we discuss how classical turbulence techniques are used to advance our understanding of clouds. The development of a physics-based turbulence closure based on asymptotic exact solutions of the equations of motion is presented. The newly developed turbulence model is used in fine-scale modeling of cloudy atmospheric boundary layers. Fine-scale cloud modeling is used to investigate the development of cloud horizontal organization, an important mechanism in the interaction of the boundary layer with the large-scale planetary circulation. Finally, we discuss how findings from high-resolution modeling of clouds are used to inform the development of convection parameterizations in climate models.

We are excited to present an invited talk at the APS Global Physics Summit 2025 next week! We are discussing our favorite topics: clouds ☁️ and turbulence 🍥 Monday March 17 in Session MAR-B45, Anaheim Convention Center, 263A (Level 2). The Session is sponsored by the Topical Group on the Physics of Climate @APS_GPC. Also, check out all the other exciting talks at the same session! Looking forward to engaging with everyone. #APSSummit25

For those attending the #AGU24 we have a poster today, Tuesday, Dec 10 about one of our favorite topics: clouds ☁️☁️☁️!!! Poster session A21C-1707: "The long road to equilibrium: Temporal scaling of marine boundary layers"

one more latte …ahem, excuse me, buoyant convection simulation, for all coffee lovers out there ☕️ as in the previous post, code, simulation and visualization by our student @jacobjivanov ☕️☕️☕️

Even the colorbar cannot contain its excitement about this cool animation of buoyant convection by our student @jacobjivanov! This was our CFD class term project last semester. Animation shows scaled temperature (top panel) and velocity magnitude+streamlines (bottom).

University Communications produced a great video highlighting our work on wind energy! We are very grateful to the Eversource Energy Center @UConnEEC for supporting this research. youtube.com/watch?v=S_ZhFUqJ…

We are excited to be DC for #apsdfd2023! Oumaima's and Obaidullah's @khawar1366 talks are Monday morning. If you are in DC, don't forget to check all the fluids art (including ours 😉) at the Traveling Gallery of Fluid Motion at the National Academy of Sciences. The coordinates for our talks are (both conveniently placed in the same session): L20: Geophysical Fluid Dynamics: Atmospheric I, Monday, 8:00 AM, Room: 146C L20.00004: Sea surface temperature and subsidence effects on steady-state stratocumulus to shallow cumulus cloud transitions L20.00006: Computational domain size effects on large-eddy simulations of precipitating shallow cumulus convection

Do you want to solve impactful real-world problems? Perhaps you should take our class – or another class @UConnEngineer

It was inspiring to spend time with artist Karen LaMonte @karenlamonte and chat about art & clouds. Many thanks to Karen for giving us some of her precious time. Check out her work — including cloud sculptures — at karenlamonte.com. In the picture Karen is signing her book

Congratulations to Dr. Oumaima @Vagalust for successfully passing her PhD defense! We could not be happier and more proud! Many thanks to all the amazing members of Oumaima's committee for their mentorship and guidance @MarinaAstitha 🎊🎊🎊

Snowboarding. Powder day at the local hill! Come shred with us!!!

Thank you @NCAR_CGD for hosting us and organizing the #CESM Workshop. It was nice to be back in Boulder! This is Oumaima @Vagalust and Obaidullah with their poster.

Check out our visualizations and those of others in this special collection in @PhysRevFluids. All articles are freely available. These articles are a great read: striking visuals, interesting problems in fluid physics, short, and accessible to non-experts in the field.
