Abstract

Flow behavior of a jet issuing from a steam inlet nozzle of a Terry turbine, which is employed in the RCIC system of BWRs, was observed using PIV techniques. The nozzle has a complicated shape and sufficient data do not exist to predict flow phenomena including exhaust jet flow behavior. Single-phase air jet flow was applied for this experiment. The jet flows 10 mm from the nozzle then impinges on a flat wall which simulates the wall segment between buckets on a turbine wheel. The nozzle outlet pressure was set as 30 psi and 40 psi. Flow behavior and collision behavior was different between the two cases, which implies nozzle outlet pressure of Terry turbine also affects the flow behavior in the turbine. The flow behavior is very important to know how Terry turbine works in BDBE condition or to estimate actual life time of the RCIC system itself. This is the first trial to clarify the behavior and further work will be done in the future.
