His thermal science background includes conduction, convection, and radiation heat transfer.  His background in fluid mechanics includes gas dynamics (theoretical and computational), boundary-layer theory, turbulent flow, potential flow, viscous flow, and fundamental fluid mechanics.

Mr. Leutwyler’s experience includes performing root-cause investigations, developing dynamic and kinematic equations of motion to predict transient performance of valves/actuators, developing analytical models to predict valve and/or actuator capability, developing and executing test procedures, performing computational fluid dynamics (CFD) analysis of butterfly, check, and globe valves of different shapes and other piping system components, performing finite element analyses (FEA) and coupled fluid-structure and thermal interactions analyses, designing test fixtures and analyzing valve modifications. 

His recent projects included performing root-cause investigations of various valve failures including main seat leakage in main steam safety relief valves (MSRV) related to marginal seat contact aggravated by thermal and mechanical loading, pilot seat leakage and setpoint drift failures in MSRVs due to marginal seat contact pressure that was sensitive to side loading and thermal distortions, and butterfly disc-pin lose due to disc flutter resulting from upstream disturbances.  The root-cause investigation of the pilot-operated MSRV main seat leakage included developing a 3-D model of the valve and performing a thermal structural analysis of the valve during system startup.  The analysis modeled the initiation and progression of the thermal distortion due to small seat leakage consistent with marginal seating capability at low system pressure.

Recent project experience also included the following: (1) modeling and analysis of swing disc type Main Steam Isolation Valves (MSIV) and Main Steam Check Valves (MSCV) under power uprate conditions using RELAP to predict disc impact velocities under pipe break and spurious closure; (2) developing methodology for stroke time predictions of a containment purge butterfly valve operated by pneumatic scotch yoke actuator under design basis conditions; (3) performing flow-loop testing on globe, butterfly, and tapered plug valves to develop valve performance prediction modeling coefficients for KVAP (the leading valve and actuator analysis program in the U.S. and Nuclear power industry); and (4) testing diaphragm actuators to determine effective diaphragm area.

Mr. Leutwyler’s experience in CFD related to valves is extensive single phase incompressible and compressible flow and two phase cavitation flow.  He has also performed experimental compressible and incompressible flow loop tests on many different types of valves, and validated CFD predictions against the test results.  His background in CFD includes modeling with several turbulence models including common two equation Reynolds-Averaged Navier-Stokes (RANS) based models like the K-e and K-w and higher order hybrid models (Detached Eddy Simulation (DES)), which combine two equation predictions in the boundary layer with higher order Large Eddy Simulation (LES) models away from the boundary.
