Numerical assessment of the inception point in different stepped spillway configurations
Published in Arabian Journal of Geosciences
Many studies on several aspects of the flow characteristics over a stepped spillway such as air entrainment, velocity profiles, and energy dissipation were mostly based on physical models and more recently with computers flagrant revolution on CFD. This latter presents clear advantage as reducing laboratory testing which leads to time optimization,...
Characteristics of Water and Urea–Water Solution Sprays
nevertheless, the overall mixing performance was not significantly affected.
Evaluation of Radiant Heating Ceiling Based on Energy and Thermal Comfort Criteria, Part II: A Numerical Study
C in a building with low-performance facades can provide optimal thermal sensations at most body parts. This study also proves that the PMV comfort model (Predicted Mean Vote index) is not at all a suitable model for the evaluation of radiant heating systems (especially if occupants have winter clothes), even if the air/operative temperature distri...
Simultaneous Verification of Multi-Ultrasonic-Flowmeters in Tandem Arrangement for Natural Gas
3 (DN150) are thereby proved, whereas the striking difference in E (~1.0%) between the most downstream UFM and the other UFMs for n = 5 (DN250), associated with the outstanding collapse onto the velocity profile along the acoustic paths, results in the invalidation of the SVUFMST.
CFD simulation and measurement of the thermal behavior inside a room of the institutional library: a comparative study
Abstract This article presents the results of the comparison between the CFD simulation and temperature measurements, both in the time domain, at a certain point of interest within a specific closed space (cubicle) of the institutional library of the Salesian Polytechnic University (UPS), at its headquarters in the city of Cuenca, Republic of Ecuad...
CFD Simulation of an Industrial Spiral Refrigeration System
the product has to be cooled efficiently to a specified temperature (often to fulfill regulatory requirements) whilst preserving its quality. This study involves the analysis of spiral cooling refrigerators used in cooling food products, in this case, Cornish Pasties. Three separate sets of CFD models were developed and validated against experiment...
Computational Method for Early-Stage Design Optimization of Naturally Ventilated Terminals
This thesis focuses on the development of a computational model for early-stage design decision support of naturally ventilated terminal structures. The model is developed in a parametric Rhino Grasshopper environment paired with Python coding and CFD analyses through OpenFOAM. Optimization of air distribution parameters is performed with Galapagos...

Mesh Deformation Using Radial Basis Function Interpolation With Sliding Boundary Nodes
This thesis studies a novel mesh deformation method based on radial basis functions to improve mesh quality in regions with small wall clearances. For fluid-structure interaction problems or imposed motion CFD problems, the usually fixed Eulerian fluid meshes have to undergo deformation to conform to the deforming structure. In such cases, it is im...
