Adaptive Simulation of the Internal Flow in a Rocket Nozzle
(Planta Piloto de Ingeniería Química, 2014-07)
This work is a first step in the understanding of the interaction process between internal shock waves and the flow transition inside of a rocket nozzle that develops during the engine start-up phase or when the nozzle is ...
Damage tolerant analysis of corner cracks in small nozzle process penetration of the CAREM-25 reactor pressure vessel
(Elsevier, 2019-12)
This paper presents a damage tolerant approach assessment of corner cracks in small nozzle process penetrations in the pressure vessel of the small modular reactor CAREM-25 subjected to mechanical and thermal shock loadings ...
Numerical modeling of the gas breakdown development in the space–charge layer inside the nozzle of a transferred arc torch
(IOP Publishing, 2012-06)
Double–arcing is a phenomenon that occurs when a transferred arc, flowing inside an electrically insulated nozzle, breaks into two separate arcs: one that connects the cathode with the nozzle, and another that connects the ...
Selección de boquillas para pulverizaciones en barbecho químico
(EEA Oliveros, INTA, 2020)
Cuando hay que definir una técnica de pulverización para cualquiera de las situaciones de trabajo a campo con equipos terrestres, son varios los aspectos a determinar.
Atomization of molten materials for particle coating: Prediction of mean droplet size for two-Fluid nozzles
(Begell House, 2016-06)
Coating is the process of covering solid particles' surfaces with a homogeneous layer of a coating agent comprising one or multiple components. For processes carried out in fluidized beds, coating is achieved by spraying ...
Numerical simulation of spray ejection from a nozzle for herbicide application: Comparison of drag coefficient expressions
(Elsevier, 2019-02)
This paper compares the different expressions of drag coefficients using a Computational Fluid Dynamics (CFD) code. This code is a Large-eddy Simulation-Lagrangian Stochastic Model (LES-STO) to simulate liquid particle ...
Continuous deposition of a liquid thread onto a moving substrate. Numerical analysis and comparison with experiments
(American Society of Mechanical Engineers, 2012-02)
The printing of a thin line of liquid onto a moving flat solid substrate was studied numerically. For a fixed value of the Capillary number, the window of steady state deposition was explored in terms of the substrate-nozzle ...
Numerical simulation of spray ejection from a nozzle for herbicide application: Evaporation and binary collision models
(Elsevier, 2020-08)
The numerical simulation of water spray ejected from HARDI™ ISO F110 03 flat fan nozzle has been performed in this work. The simulation models of ejection and trajectory of liquid droplets proposed in previous study are ...
A constant-pressure model for the overlap of chambers in rotary internal combustion engines
(American Society of Mechanical Engineers, 2016-11)
In this work, a constant-pressure model capable to simulate the overlap of chambers in rotary internal combustion engines is proposed. It refers as a chamber overlap when two adjacent chambers are in communication through ...
