вЂprogramme to step the stepper motor CW in Full Step mode which gives 200steps/rev 'В вЂspecify that we are using the Basic Stamp 2 module The results presented qualitatively agree with those reported by Bau and Torrance (1981) for an open U-shaped loop. Furthermore, the number of oscillations before the steady state increases as Q Л† is increased. In general, an increase in the dimensionless heating rate Q Л† corresponds to a shorter quiescent state and a reduction in the peak (and in the steady state value) of the dimensionless temperature difference at the cooler. The temperature oscillations are damped with different features, depending on the heat input rate, until a steady state (and a constant flow rate) is achieved. These considerations are reflected in the oscillating behaviour of the temperature difference О”ГЋ, which results from the time lag between the heating process and the subsequent generation of a buoyancy force. In turn, the cold fluid first enters the heater and then rises in the ascending leg causing a deceleration of the flow. The ascending warm pulse accelerates the fluid causing a rapid increase of the flow rate until the first, peak of О”ГЋ is reached. Let us note that О”T is measured between C and D sections of Fig.1.ДЄs it can be observed from the Figs.2 and 3, after a quiescent state (О”ГЋ=0) the temperature difference О”ГЋ begins to rise, pointing out the starting of unidirectional flow through the loop.
