Laminar shear
WebbHere, we show that laminar flow exposure reduced glucose uptake and mitochondrial content in endothelium. Shear stress-mediated reduction of endothelial metabolism was reversed by silencing the flow-sensitive transcription factor Krüppel-like factor 2 (KLF2).

Each dot represents a DAR. Laminar flow is a flow regime characterized by high momentum diffusionand low momentum convection. When a fluid is flowing through a closed channel such as a pipe or between two flat plates, either of two types of flow may occur depending on the velocity and viscosity of the fluid: laminar flow or turbulent flow. Visa mer In fluid dynamics, laminar flow is characterized by fluid particles following smooth paths in layers, with each layer moving smoothly past the adjacent layers with little or no mixing. At low velocities, the fluid tends to … Visa mer The type of flow occurring in a fluid in a channel is important in fluid-dynamics problems and subsequently affects heat and mass transfer in fluid systems. The dimensionless Visa mer Laminar airflow is used to separate volumes of air, or prevent airborne contaminants from entering an area.
