Experimentally validated pre-design maps and performance estimation methods for small-scale turbopumps for organic rankine cycles

Jürg Alexander Schiffmann, Sajjad Zakeralhoseini

The organic Rankine cycle (ORC) system is considered a promising technology to exploit thermodynamic potential of waste heat. Small-scale ORC applications, including both vehicular applications and stationary power plants, would greatly benefit from more c ...

LDP and CLT for SPDEs with transport noise

Lucio Galeati

In this work we consider solutions to stochastic partial differential equations with transport noise, which are known to converge, in a suitable scaling limit, to solution of the corresponding deterministic PDE with an additional viscosity term. Large devi ...

Experimental Investigation of Hydraulic Fracture Closure in a Porous Sandstone

Brice Tanguy Alphonse Lecampion, Seyyedmaalek Momeni, Guanyi Lu, Mohsen Talebkeikhah

Depending on the type of fracture propagation regime when the injection stops, the closure of the fracture may occur exactly after the injection ceases, in the case where the fracturing process is dominated by fracture energy, or the fracture propagate for ...

Direct numerical simulation of evaporation and condensation with the geometric VOF method and a sharp-interface phase-change model

Lubomír Bures

The paper describes a coupling of the geometric Volume-of-Fluid (VOF) method with a sharp-interface phase-change model for Cartesian and axisymmetric grids. Both the interfacial position and the temperature field are resolved with subgrid accuracy. Species ...

Reduced-order Models for Simulating Coupled Geometric Instabilities in Steel Beam-columns Under Inelastic Cyclic Straining

Alexander Riley Hartloper

Numerical models that can simulate coupled geometric instabilities in steel beam-columns are required for the seismic assessment of certain steel moment-resisting frames. Reliably simulating coupled instabilities requires that the steel material is precise ...

Immersed boundary-conformal isogeometric method for linear elliptic problems

Annalisa Buffa, Pablo Antolin Sanchez, Xiaodong Wei

We present a novel isogeometric method, namely the Immersed Boundary-Conformal Method (IBCM), that features a layer of discretization conformal to the boundary while employing a simple background mesh for the remaining domain. In this manner, we leverage t ...

Swirl number based transposition of flow-induced mechanical stresses from reduced scale to full-size Francis turbine runners

François Avellan, Arthur Tristan Favrel, Christian Landry, Joao Gomes Pereira Junior, Keita Yamamoto

At part load conditions, Francis turbines are subject to the emergence of a hydrodynamic instability in their draft tube, referred to as precessing vortex rope. It induces pressure pulsations in the water passages at the precession frequency of the vortex, ...
