It influences hemostasis, thrombosis, atherosclerosis and endothelial cell behavior by modulating platelet deposition, ion channel activation and gene expression. To study these processes in vitro, flow chambers such as the ibidi µ-Slide VI0.4 are widely used, enabling cell culture under defined shear stress and live-cell imaging. While typically applied at WSS ≤1 Pa, usage with higher stresses have also been reported in literature. During our experiments, however, we observed inhomogeneous flow in the ibidi µ-Slide VI0.4.MethodsTo confirm these observations, a Computational Fluid Dynamic simulation of the flow chamber was conducted. The simulation was first validated by PIV experiments in the center layer of the channel at two different volume flows. The results were compared to the numerical simulation and the analytical results, which are based on the manufacturer’s application note with reference to literature.ResultsIn contrast to the analytical results and the manufacturer’s specifications, the numerical results show velocity variations in the center layer of the channel, which increase with higher volume flow. This phenomenon is confirmed by experimental data. Simulation of the WSS on the channel bottom shows that, at low volume flows, WSS is relatively homogeneous and matches expected values. However, inhomogeneities increase with higher flow above 23.66 mL/min, where the deviation from the expected WSS is 10%. The data also reveal relatively high WSS near the lateral walls of the channel as well as increased velocities near the channel bottom at the inlet area. This results in secondary flow and inhomogeneous velocities at the wall along the channel.ConclusionThis study highlights limitations of the ibidi µ-Slide VI0.4 at elevated WSS. The findings indicate that increasing volume flow leads to heterogeneous wall conditions, which may strongly influence cell experiments.]]> https://www.frontiersin.org/articles/10.3389/fmech.2026.1798368 https://www.frontiersin.org/articles/10.3389/fmech.2026.1798368 <![CDATA[Physics-guided machine learning for predicting wind pressure on a vibrating square prism]]> 2026-05-07T00:00:00Z Original Research Yingying HeYu ZhangLikai ZhangGuoqing LiChunlun JiangZhengquan LiWenwu Li https://www.frontiersin.org/articles/10.3389/fmech.2026.1809868 https://www.frontiersin.org/articles/10.3389/fmech.2026.1809868 <![CDATA[Correction: Analysis of fluid flow across a 2D bluff body in a tandem arrangement with varying aspect ratios near a moving wall]]> 2026-04-07T00:00:00Z Correction Pawan Kumar PantSunil ChamoliNaval PantHitesh JoshiSaurav RanaManoj Kumar PathakVaresa ChuwattanakulSmith Eiamsa-ard https://www.frontiersin.org/articles/10.3389/fmech.2026.1780728 https://www.frontiersin.org/articles/10.3389/fmech.2026.1780728 <![CDATA[Design of a micrometer-scale multilayer air filter]]> 2026-03-18T00:00:00Z Original Research Fenglong YinYuehao LiXinyi ZhangYanxia LiXiaodong Liang https://www.frontiersin.org/articles/10.3389/fmech.2026.1740843 https://www.frontiersin.org/articles/10.3389/fmech.2026.1740843 <![CDATA[Considering surface roughness O-ring lubricating-oil static seal leakage prediction via optimized circular plate gap model]]> 2026-03-02T00:00:00Z Original Research Zhengquan WuGuo-hai Zhuo https://www.frontiersin.org/articles/10.3389/fmech.2026.1761460 https://www.frontiersin.org/articles/10.3389/fmech.2026.1761460 <![CDATA[Propagation characteristics of H2–air detonations in double-bend ducts]]> 2026-02-10T00:00:00Z Original Research Yuhan WangChun ZhengHuanhao ZhangZhihua Chen https://www.frontiersin.org/articles/10.3389/fmech.2025.1727981 https://www.frontiersin.org/articles/10.3389/fmech.2025.1727981 <![CDATA[Analysis of fluid flow across a 2D bluff body in a tandem arrangement with varying aspect ratios near a moving wall]]> 2026-02-03T00:00:00Z Original Research Pawan Kumar PantSunil ChamoliNaval PantHitesh JoshiSaurav RanaManoj Kumar PathakVaresa ChuwattanakulSmith Eiamsa-ard https://www.frontiersin.org/articles/10.3389/fmech.2025.1651334 https://www.frontiersin.org/articles/10.3389/fmech.2025.1651334 <![CDATA[Fluid flow and mass transport along a microchannel with physics-informed neural networks]]> 2026-01-21T00:00:00Z Original Research Mehmet Melih TatlisozCetin Canpolat https://www.frontiersin.org/articles/10.3389/fmech.2025.1717775 https://www.frontiersin.org/articles/10.3389/fmech.2025.1717775 <![CDATA[Quantum Lattice Boltzmann Method based on linear equilibrium distribution functions]]> 2026-01-16T00:00:00Z Original Research Zhengliang LiuBenzi JohnDavid R.
