This paper presents a novel approach combining high-speed thermographic measurements with heat-flux compensation methods to evaluate aerodynamic heating on a hypersonic projectile, demonstrating that the experimentally derived stagnation Stanton number aligns with both computational fluid dynamics simulations and empirical correlations.
This paper introduces a "Lego Block" methodology that combines Schwarz-Christoffel maps and segmentation techniques to construct analytical solutions for fluid flow in complex microfluidic networks and disordered media governed by Laplace's equation, enabling the modeling of multiply connected domains with minimal numerical computation.
This paper proves the existence and uniqueness of a global solution to the two-dimensional incompressible Navier-Stokes equations in a half-plane with no-slip boundary conditions and point vortex initial data for any Reynolds number, by decomposing the solution into a vortex and a boundary layer term to overcome the challenges posed by large circulation without requiring smallness conditions on the initial vorticity.
This study experimentally demonstrates that deep-water gravity-wave solitons can coexist with classical linear diffraction, maintaining their longitudinal solitonic character while undergoing transverse reshaping governed by Fresnel laws.
This paper presents NeuralFVM, a GPU-accelerated neural-physics solver that reformulates the finite volume method with the - turbulence model using local tensor operations and operator-splitting to achieve significant speedups while maintaining accuracy comparable to commercial CFD software.
This study introduces a novel background-oriented schlieren (BOS) technique with ray-tracing correction to quantitatively measure spatiotemporal shock wave-droplet interactions, successfully validating experimental density-gradient and pressure fields against numerical simulations and capturing previously hypothesized phase shifts during shock focusing.
This paper reveals a universal nonlocal energy transfer mechanism in three-dimensional zero-temperature quantum turbulence that bypasses the classical Kolmogorov cascade by directly transferring energy from large to very small scales through the alignment of quantum vortices with large-scale velocity gradients.
This study experimentally and numerically investigates self-sustaining, bibrachial rotating methane-air flames in a circular Hele-Shaw cell, revealing how wall heat loss and flow expansion stabilize traveling-wave patterns across various flow rates and equivalence ratios to inform micro-combustion technology.
This paper demonstrates that periodically textured microchannel walls can passively align elongated microparticles along the centerline through geometry-driven shear gradients, offering a robust framework for designing microfluidic devices to sort or focus anisotropic particles across various flow regimes.
This study demonstrates that at high Reynolds numbers, time-varying wind-turbine wakes propagate as nonlinear traveling waves that can be accurately described by a quasi-steady Lagrangian transformation, revealing that wake advection is critical for wind-farm modeling and that time-varying control can optimize farm performance even under nominally steady conditions.
