Vapour generation from the impellers in boiling stirred tank reactors

Change in liquid temperature behind the impeller blades with impeller speed in boiling stirred tanks

“…(4) we can evaluate ( ˘f − b ) ave from the measured power consumption, P. The data for P in the boiling stirred tank with the dual impeller systems are presented in Fig. 2 of our previous paper (Fukuda et al, 2009). Similar results were obtained for the triple impeller systems.…”

“…The model predictions are compared with the liquid temperatures measured using the thermocouple attached to the back of the impeller blade in our previous study (Fukuda et al, 2009).…”

“…Dual and triple impeller configurations, which For triple impeller configurations, they were 0.15 m and 0.05 m, respectively. All other detailed aspects of the experimental work including the configuration of the stirred tank and the measurements of liquid temperature behind the impeller blade and power consumption are described in our previous paper (Fukuda et al, 2009). …”

“…The vapour generation from the impellers in boiling stirred tanks might be controlled by the local liquid temperature and vapour pressure. In our previous paper (Fukuda et al, 2009), therefore, we measured the liquid temperature behind the impeller blades and it was found to decrease with increasing impeller speed.…”

“…We examined the validity of the proposed model using measured local liquid temperatures with dual and triple impeller systems in our previous study (Fukuda et al, 2009). …”
