Air expulsion analysis of an industrial air valve using CFD
(
Institute of Electrical and Electronics Engineers Inc.
, 2021 , Conference Paper)
CFD (Computational Fluid Dynamic) analysis is a modern technique to estimate and determine fluid characteristics. CFD uses the Navier-Stokes equation to solve complex fluid behavior along with turbulence models such as k- ...
Areadynamic analysis of GMC sierra pickup truck
(
Institute of Electrical and Electronics Engineers Inc.
, 2021 , Conference Paper)
Computational Fluid Dynamics (CFD) was used to simulate the flow field over a GMC sierra pickup truck double cab (manufactured year of 2005). This simulation model was compared to a previous simulation and experimental ...
Global evaluation of WBGT and SET indices for outdoor environments using thermal imaging and artificial neural networks
(
Elsevier
, 2020 , Article)
The health and well-being of occupants of outdoor environments are largely affected by thermal stress, and therefore a global assessment is essential. Wet-bulb globe-temperature (WBGT) is used as a heat stress indicator ...
Optimization of reliability and maintenance of liquefaction system on FLNG terminals using Markov modelling
(
Emerald Group Publishing Ltd.
, 2014 , Article)
Purpose: The purpose of this paper is to optimize system redundancy and maintenance intervals of a propane pre-cooled mixed refrigerant (C3MR) liquefaction process on floating liquefied natural gas (FLNG) export platforms. ...
A novel robust automated FFT-based segmentation and features selection algorithm for acoustic emission condition based monitoring systems
(
Elsevier
, 2015 , Article)
This paper aims at developing a robust, fast-response and automated FFT-based features selection algorithm for the development of acoustic emission practical condition based monitoring applications of mechanical systems. ...
Effect of individually controlled personalized ventilation on cross-contamination due to respiratory activities
(
Elsevier
, 2021 , Article)
While personalized ventilation (PV) has been integrated to enhance inhaled air quality, some studies showed that it can contribute to contaminants' transport indoors. This work investigates the effect of the individual ...
Numerical evaluation of the thermal performance of a near-surface earth-to-air heat exchanger with short-grass ground cover: A parametric study
(
Elsevier
, 2021 , Article)
High energy consumption and increasing energy cost have encouraged investment in energy efficiency. In hot areas, like the Middle East, the share of space cooling accounts for most of the total energy use in buildings. ...
Assessment of thermal comfort indices in an open air-conditioned stadium in hot and arid environment
(
Elsevier
, 2021 , Article)
Thermal comfort indices are vital tools when assessing outdoor thermal comfort in hot and arid environments. Selecting a representative thermal comfort index for outdoor environments is challenging. This paper presents a ...
A novel hydrogen liquefaction process using dual mixed cryogenic refrigeration system: Energy, exergy, and economic analysis
(
Elsevier
, 2024 , Article)
In conventional hydrogen liquefaction plants, the liquefaction process consumes high portion of about 30 % of the liquid hydrogen (LH2) energy content. In addition, existing LH2 technology uses pure or single mixed ...
Hybrid ejector-absorption refrigeration systems: A review
(
MDPI
, 2021 , Article Review)
Absorption Refrigeration Systems (ARS) are potential alternatives to direct expansion (DX) refrigeration systems. This review focused on the incorporation of an ejector into absorption refrigeration cycles to constitute ...
