    • Cooling Water Pump Station Optimization Using CFD and Physical Model Test 
      Annese, Francesco; Ficele, Letizia; Lisanti, Emanuele (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
      In this paper, a combined study between Computational Fluid Dynamics (CFD) and a model test has been carried on a Cooling Water Pumping Station as part of a new power plant. The aim of this work was to validate a water pit ...
    • L10: A FEM Approach to Predict Acoustic Resonance in Multistage Centrifugal Pump 
      Bruno, Simone; Annese, Francesco; Brizzi, Rita (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2021)
      Acoustic resonance can develop within the hydraulic channels of the pump, especially in the long crossover channel of a multistagecentrifugal pump This phenomenon occurs when the hydraulic channel length is equal to the ...
    • L120: THERMO-STRUCTURAL TRANSIENT ANALYSIS OF A BOILER FEEDWATER PUMP 
      Giulio, Elicio; Annese, Francesco (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries; Texas A & M University. Libraries, 2021)
      In the last few years, the installed capacity and production of electricity from all the renewable energies have significantly risen, supported by an ever-increasing spread of new energy policies all around the world. ...

    • PL05 - A FEM APPROACH TO PREDICT ACOUSTIC RESONANCE IN MULTISTAGE CENTRIFUGAL PUMP 
      Bruno, Simonne; Annese, Francesco; Brizzi, Rita (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries, [2019])
      Acoustic resonance that can develop within the hydraulic channels of the pump, especially in the long crossover channel of a multistage, has always had in the past a minimal consideration if compared with other dynamic ...
    • Thermo-Structural Analysis Of Steam Tracing Arrangements Applied To Pump Barrels 
      De Francesco, Francesco; Annese, Francesco; Da Soghe, Riccardo; Mazzei, Lorenzo; Brizzi, Rita (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries, 2022)
      Pumps steam tracing is widely used in Oil&Gas industry for critical services in which the process fluid requires a minimum temperature to avoid its crystallization during stand-by. This paper describes the process of ...
    • Vibration and NPSHr (NPSH₃), improvement of BB1 two stage pump reliability 
      Annese, Francesco; Brizzi, Rita; Guastamacchia, Paolo; Yahaya, Mohamad Raba'i (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries; Texas A & M University. Libraries, 2020)
