Experiments on Melt Dispersion with Lateral Failure in the Bottom Head of the Pressure Vessel
نویسندگان
چکیده
Melt dispersion experiments with lateral failure in the bottom head were carried out in a 1:18 scaled annular cavity design under low pressure conditions. Water and a bismut-alloy were used as melt simulant material and nitrogen as driving gas. With lateral breaches the liquid height in the lower head relative to the upper and lower edge of the breach is an additional parameter for the dispersion process. Shifting the break from the central position towards the side of the lower head leads to smaller melt dispersion, and a larger breach size does not necessarily lead to a larger dispersed melt fraction.

Low Pressure Corium Dispersion Experiments with Lateral Failure in the Bottom Head of the Pressure Vessel
Experiments were performed in a scaled annular cavity design, to investigate melt dispersal from the reactor pit when the reactor pressure vessel lower head fails at low system pressure of less than 2 MPa. In the part of the experimental program presented in this paper, the fluid dynamics of the dispersion process was studied using model fluids, water or bismuth alloy instead of corium, and nit...
متن کاملImpact of Blood Vessel Wall Flexibility on the Temperature and Concentration Dispersion
The analysis of solute and thermal dispersion in pulsatile flow through the stenotic tapered blood vessel is presented. The present problem is an extension of the work done by Ramana et al. who considered the time-invariant arterial wall. In the present model, the flexible nature of the arterial wall through the obstruction (called stenosis) is considered and it is achieved with the he...

Background: Endotracheal tube cuff pressure must be maintained in safe range. Many factors could be affecting on endotracheal tube cuff pressure in patients on mechanical ventilation. Patients undergoing mechanical ventilation (MV) in critical care settings require changing position for different reasons. The aim of this study was to determine the effect of changes in body position and head of ...

Objective: there are still disputes over the effect of using slope strategy on the reduction of peak pressure and time of pressure on the foot. Therefore, the objective of this study was to evaluate the effect of internal and external wedge slope changes on the mechanical parameters of foot ulcers. Methods: In this quasi-experimental study 15 diabetic patients with an average age of 63.3&plusm...

Background & Aims: Tracheal intubation with a cuffed tube for the administration of general anesthesia is routine. The cuff of the endotracheal tube is inflated with air to achieve an adequate seal to prevent aspiration and leakage of air and anesthetic gases. Whereas over-inflation can decrease the mucosal perfusion, leading to pressure necrosis and nerve palsies. This study aimed to evaluate ...
