A simple impurity model has been developed under the BOUT++ framework to investigate the Li-pellet triggered edge localized mode (ELM) in EAST configuration. The present impurity model decouples the ion pressure enhancement effect (IPEE) (which affects radial E $ \times $ B flow shear and gyro-viscosity of deuterium ions and is implicitly included in our previous work) to make the sim... https://jalyttlers.shop/product-category/cable-suspension/
