The drying of sewage sludge is a current environmental problem, not suffi ciently described in the literature. Hence, the aim of this work is a numerical study of heat and mass transfer under solar drying of residual sludge. This sludge is assimilated to a porous medium and exposed to a forced convection laminar fl ow within a horizontal channel. T...

Thesis
Full-text available
Le séchage des boues d'épuration est un problème environnemental actuel, qui n'est pas suffisamment décrit dans la littérature. Par conséquent, ce travail représente une étude numérique des transferts de chaleur et de masse lors du séchage solaire des boues d’épuration. Cette boue est assimilée à un milieu poreux et exposée à un écoulement laminair...
Article
Sewage sludge presents a real problem with the urban and industrial expanding. So, the drying technique is indispensable in the sludge treatment process to minimize its volume and its revalorization. For cost and environmental reasons, the solar drying is becoming increasingly attractive for small and medium wastewater treatment plants. Therefore,...

The present work is a numerical study of heat and mass transfers during solar drying of sewage sludge treated as a porous media. This medium is placed inside a horizontal channel exposed to a forced convection laminar air flow. The transfers in the channel and in the porous medium are respectively described by the classical equations of forced conv...

Conference Paper
Le présent travail consiste à étudier numériquement les transferts de chaleur et de masse lors du séchage solaire de boues assimilées à un matériau poreux. Ce milieu poreux est placé à l'intérieur d'un canal horizontal exposé à un écoulement laminaire d'air en convection forcée. Les transferts dans le canal et dans le milieu poreux sont décrits res...
Conference Paper
This work aims to numerically investigate the heat transfer characteristics of a semi-circular cylinder immersed in confined flow. The numerical simulations were performed using the CFD code Fluent under the assumption of a two-dimensional incompressible flow in unsteady laminar regimes with presence of thermal exchange. This study allowed us to de...
