Natural convection heat transfer of nanofluids along a vertical plate embedded in porous medium

Ziya Uddin, Souad Harmand

The unsteady natural convection heat transfer of nanofluid along a vertical plate embedded in porous medium is investigated. The Darcy-Forchheimer model is used to formulate the problem. Thermal conductivity and viscosity models based on a wide range of experimental data of nanofluids and…

Onset of atomization on horizontal, shear-driven liquid films at the vicinity of a sharp corner

Evangelos Bacharoudis, Hervé Bratec, Laurent Keirsbulck, Jean-Marie Buchlin, Larbi Labraga

In many engineering applications, the liquid films have to deal with sudden changes of the wall geometries in which they flow over. The present work concerns the study of the onset of the film atomization in corner geometries. Specifically, films with thickness in the range of 1 mm < hf < 2.5…

Inducing Swirling Flow in Heat Exchanger Pipes for Reduced Fouling Rate

Halldor Pálsson, François Beaubert, Sylvain Lalot

Fouling buildup in circular heat exchanger pipes is a common problem in the industry. Various methods have been proposed to increase the shear stress of the fluid near the pipe wall. This is known to reduce fouling rate, as well as increasing the heat transfer rate of heat exchangers. In this…

Understanding soft evidence as probabilistic evidence : illustration with several use cases

Ali Ben Mrad, Véronique Delcroix, Sylvain Piechowiak, Mohamed-Amine Maalej, Mohamed Abid

This paper aims to get a better understanding of the notions of evidence, probabilistic evidence and likelihood evidence in Bayesian Networks. Evidence comes from an observation of one or several variables. Soft evidence is probabilistic evidence, since the observation consists in a local…

Open-People: Open Power and Energy Optimization PLatform and Estimator

Eric Senn, Daniel Chillet, Olivier Zendra, Cécile Belleudy, Sebastien Bilavarn, Rabie Ben Atitallah, Christian Samoyeau, Agnès Fritsch

Designing low power complex embedded systems is now a critical challenge for a large number of electronic corporations. Low power is generally critical due to its impact on lifetime, battery longevity, battery capacity, temperature constraints, etc. Unfortunately, when a designer needs some power…

Fault diagnosis and monitoring of oscillatory failure case in aircraft inertial system

Denis Berdjag, Jérome Cieslak, Ali Zolghadri

A method for oscillatory fault detection and isolation is presented and used to detect oscillatory failures of redundant aircraft sensors involved in the computation of flight control laws. The objective is to switch off the erroneous sensor and to compute a consolidated parameter using data from…

High order sliding mode control for hybrid vehicle stability

Sebastien Delprat, Alejandra Ferreira de Loza

This paper tackles the problem of driving stability for a hybrid vehicle. A rear electric motor has been added to the vehicle driveline and the positive/negative torque generated by this motor affects the driving conditions. The vehicle stability control is addressed using high order sliding modes…
