A COMPUTATIONAL STUDY ON FREE CONVECTION FOR THERMAL PERFORMANCE EVALUATION OF A SWNT THIN-FILM HEATER

SWNT 투명박막히터의 열성능 평가를 위한 자유대류 열전달 해석

A computational investigation is conducted on free convection from a thin plate having a surface heat source. The thermal configuration simulates the recently-proposed transparent film heater made of a single-walled carbon nanotube film on a glass substrate. The Navier-Stokes computations are carried out to study laminar free convection from the heater. Parallel numerical experiments are performed by using a simplified design analysis model which solve the conduction equation with the boundary conditions utilizing several existing correlations for convective heat transfer coefficient. Comparison leads to the most suitable boundary condition for the thermal model to evaluate the performance evaluation of a transparent thin-film heater.
