Abstract

In this study, the thermal behaviour of insulating building walls and energy savings were determined in Er-Rachidia, located in south-east Morocco. Specifically, the study evaluates the effectiveness of clay-based insulation materials reinforced with palm leaves pinnate (PLP) and clay and palm trunk (PT). The results indicate that a 4 cm thick clay insulation material reinforced with PLP increases the winter temperature by 1°C and decreases it by 0.9°C in summer compared to room temperature. Furthermore, it demonstrates a remarkable 33% reduction in heating consumption and a 44% reduction in air-conditioning consumption, leading to an overall 35% reduction in total energy consumption. In contrast, the clay and PT reinforced clay insulation materials exhibit a 16% and 21% reduction in energy consumption, respectively.

Abstract

In this paper, a thermal performance assessment of traditional building constructions and configurations in various Moroccan climates is carried out. This research focuses on enhancing conventional energy efficiency of buildings by investigating the thermal behavior of single clay walls, double clay walls, simple brick walls, and double brick walls based on long-term meteorological data using TRNSYS software. The roof pitch, thermal comfort and discomfort index, and building energy consumption are considered while selecting buildings for each temperature zone. It is noticed that the double brick construction is more efficient in all climatic zones of Morocco. Thus, this material reduces the yearly energy requirement of building by 22% to 25% compared to the usual brick building. On the coldest winter days, a 30° south-facing roof raises the internal temperature by 2.5 °C compared to a horizontal roof. Temperature increases could reduce the air conditioning energy usage by 7% to 32% and overcooling hours by 12% to 21% in cities above 30° N. In addition, the findings are interesting enough to inspire individuals to implement the recommended construction design and study energy efficiency and thermal comfort in Moroccan buildings. Consequently, reducing energy consumption, mitigating climate change, and lowering greenhouse gas emissions. [ABSTRACT FROM AUTHOR]

Abstract

The main objective of the work undertaken in this paper is to study the possibility of optimizing the flow structure and thermal performance of a heat exchanger numerically. For this purpose, the nanofluid water-Al 2 O 3 is chosen as the cooling fluid, which is in forced convective and laminar flow in a two-dimensional rectangular microchannel. Then, as a first step, the impact of the chosen nanoparticles' concentration in the range was studied: (0 ⩽ Φ ⩽ 0, 04). The Nusselt number and the coefficient of friction were analyzed. The results show that the thermal performance has been remarkably improved (more than 40%). These results are mainly due to increased effective thermal conductivity and viscose coolant (nanofluid). In a second step, the impact of the solid diamond blocks' insertion in the initially laminar flow was analyzed. The inserts' presence strongly disturbed the flow and caused a modification of its structure (velocity field, temperature field, etc.). The results show that for the same concentration of corpuscles, the average Nusselt number and friction coefficient increase much more with the Reynolds number's rise compared to the case without inserts. The study has thus allowed us to show that a nanofluid of high concentration can best adopt as the cooling fluid of a heat sink, and such a heat sink with diamond inserts has the best thermohydrodynamic performance (more than 40% increase). The differential equations system's resolution governing the problem is ensured by a finite volume scheme associated with the SIMPLE algorithm (Semi Implicit Method for Pressure Linked Equation). The study performed with a Reynolds number chosen in a range corresponding to the laminar regime: (600 ⩽ Re ⩽ 1400). The concentration of the nanoparticles taken in the field: (0 ⩽ Φ ⩽ 0.04) corresponding to the validation range of formulas (7) and (9).

Abstract

International audience; Nomex honeycomb structures are attracting increasing interest from many industrial sectors andtheir use is becoming more widespread. These structures are widely used in sandwich materials aslightweight structures having good mechanical properties. Due to its manufacture the machining ofNomex honeycomb structures present many technical and scientific problems, specifically the lowthickness of the walls constituting the honeycomb cells, the composite nature of the paper forming theNomex and low density of this type of these structures. The objective of this work is to implement ascientifically rigorous approach to predict and analyze the machinability of this type of material. Avalidation of the model was made through experimental studies with different cutting conditions.Then, a follow-up of the cutting forces and observations of the machined surface quality, using theisotropic elastoplastic approach.
