Anisotropic Surface Microrollers for Endovascular Navigation: A Computational Analysis with a Case Study in Hepatic Perfusion

Advanced Theory and Simulations, EarlyView.
Computational fluid dynamics analyses assess the upstream locomotion performance of anisotropic microrollers with varying height‐to‐width ratios. Observing their successful upstream locomotion in veins, their performance in hepatic circulation is investigated for treating primary liver cancer.

A New Wave in CFD [PDF]

Mechanical Engineering, 1998
The convergence of virtual reality, parallel processing, and Internet access is enabling computational-fluid-dynamics (CFD) codes to model complex problems in the process and petroleum industries. Improved user interfaces are making it easier for non-specialists to use CFD to investigate the conditions under which flammable or poisonous gases, to ...

Leveraging Transfer Learning to Overcome Data Limitations in Czochralski Crystal Growth

Advanced Theory and Simulations, EarlyView.
A data‐driven framework combining Computational Fluid Dynamics (CFD) simulations and machine learning is proposed to model and optimize Czochralski crystal growth. Using different transfer learning strategies (Warm Start, Merged Training, and Hyperparameter Transfer) the study demonstrates improved predictions for Ge and GaAs growth from Si‐trained ...

Heat Transfer in a Loop Heat Pipe Using Fe2NiO4-H2O Nanofluid

MATEC Web of Conferences, 2017
Nanofluids are stable suspensions of nano fibers and particles in fluids. Recent investigations show that thermal behavior of these fluids, such as improved thermal conductivity and convection coefficients are superior to those of pure fluid or fluid ...

On spurious behavior of CFD simulations

International Journal for Numerical Methods in Fluids, 1997
The authors present four numerical studies: (i) a one-dimensional chemically relaxed nonequilibrium flow calculation; (ii) a direct numerical simulation of two-dimensional incompressible flows over a back-facing step; (iii) a loosely coupled approach for a two-dimensional fluid-structure interaction; (iv) a three-dimensional unsteady compressible ...

On the strong scalability of maritime CFD [PDF]

Journal of Marine Science and Technology, 2017
Since 2004, supercomputer growth hasbeen constrained by energy efficiency rather than raw hardware speeds. Tomaintain exponential growth of overall computing power, a massive growth inparallelization is under way. To keep up with these changes, computationalfluid dynamics (CFD) must improve its strong scalability – its ability tohandle lower cells-per ...

Targeting Cystine Metabolism in the Lung Cancer Environment Enhances the Efficacy of Immune Checkpoint Inhibition

Advanced Science, EarlyView.
The tumor‐associated macrophages (TAMs) in lung cancer tissues exhibit active cystine metabolism. Restricting cystine concentration in macrophages induces M1 phenotypic polarization and upregulation of PD‐L1 expression through the GSH‐NF‐κB signaling pathway.

A Small Perturbation CFD Method for Calculation of Seal Rotordynamic Coefficients

International Journal of Rotating Machinery, 1996
Seal rotordynamic coefficients link the fluid reaction forces to the rotor motion, and hence are needed in the stability calculations for the overall rotating systems.
