The thermal injury analysis of skin tissue with a new nonlocal dual phase lag model
Xiaoya Li, Xiaogeng Tian
Abstract
Skin burning or skin thermal damage caused by heat from flash fire or contact with hot plates are the most commonly encountered hazards in daily life and industry. In this work, we investigate the temperature distribution and thermal damage of skin tissue under the action of a moving heat source. The governing equations with the moving heat source are formulated in the context of a new nonlocal dual phase lag model and solved by Laplace transformation. The influences of heat source velocity, lagging time, and nonlocal length on the temperature and thermal damage are discussed and represented graphically.
