DESCRIPTION

Transient Thermal Response. Transient Models Lumped: Tenbroek (1997), Rinaldi (2001), Lin (2004) Introduce C TH usually with approximate Green’s functions; heated volume is a function of time (Joy, 1970) Finite-Element methods. Instantaneous T rise. - PowerPoint PPT Presentation

1Transient Thermal ResponseTransient ModelsLumped: Tenbroek (1997), Rinaldi (2001), Lin (2004)Introduce CTH usually with approximate Greens functions; heated volume is a function of time (Joy, 1970)Finite-Element methods

Temperature evolution of a step-heated point source into silicon half-plane (Mautry 1990)Simplest (~ bulk Si FET)Instantaneous T rise

Due to very sharp heating pulse t V2/3/

More generalTemperature evolution anywhere (r,t) due to arbitrary heating function P(0
