Airflow through the slot from the lower surface maintains a favorable pressure gradient over the fore element of the slotted airfoil. Credit: NASA As NASA evaluates natural laminar flow for potential ...

Part I in the October 2002 issue began to unravel the mystery of deciphering airflow numbers that are derived from flow bench testing. We addressed the question, "Why test for airflow?" and detailed ...

Flow-style batteries are demonstrating the potential to dramatically cut the cost of energy storage. A rapid prototyping and test system developed by Pacific Northwest National Labs uses a ...

The rheology of powders is vitally important. The rheology and flowability of a powder can affect many of its properties, from its behavior in specific mediums to how it packs as a solid. The ...
