THERMAL RECEPTIVITY OF UNSTABLE LAMINAR-FLOW WITH HEAT-TRANSFER

In this study, open questions about the temperature disturbances in li near stability theory are addressed. Temperature effects on flow stabi lity have been investigated previously either by assuming a time indep endent shape for the temperature disturbance or by neglecting temperat ure fluctuations completely. Treating temperature fluctuations as an i nitial value problem can show the limits in which these assumptions ar e justified. By means of an asymptotic approach, based on small heat t ransfer rates, the various effects can be well separated from each oth er. (C) 1997 Elsevier Science Ltd.
