Author(s) : MOHAMMADI S. S., GRABOSKI M. S., SLOAN E. D.
Type of article: Article
Summary
ANALYTICAL SOLUTIONS FOR THREE HEAT GENERATION FUNCTIONS (DIRAC, STEP AND RAMP) ARE PRESENTED. THE RAMP HEAT GENERATION FUNCTION IS SHOWN TO OFFER SEVERAL ADVANTAGES OVER THE STEP FUNCTION, WHICH IS CURRENTLY USED BY EXPERIMENTERS. EXPRESSIONS FOR THE CORRECTIONS TO THE IDEALIZED MODEL OF A RAMP FORCED SYSTEM ARE PRESENTED FOR: HEAT CAPACITY EFFECT, TRUNCATION ERROR, NON-UNIFORM WIRE RADIUS, BOUNDED MEDIA, KNUDSEN EFFECTS, AXIAL CONDUCTION, FREE CONVECTION AND RADIATION.
