Energy and exergy analyses of novel supercritical CO2 Brayton cycles driven by direct oxy-fuel combustor
(
Elsevier
, 2021 , Article)
This study addresses major research gaps related to supercritical carbon dioxide (sCO2) power cycles including the shortcomings due to adding extra components, the high operating temperatures and the lack of studies on ...
Rupture of an industrial gfrp composite mitered elbow pipe
(
MDPI AG
, 2021 , Article)
This paper examines the immature rupture of glass fiber reinforced plastic composite (GFRP) mitered elbow pipes. The GFRP composite mitered elbow pipe’s lifespan was twenty-five years; however, the pipes in question ...
Accurate prediction of dynamic viscosity of polyalpha-olefin boron nitride nanofluids using machine learning
(
Elsevier
, 2023 , Article)
This study focuses on predicting the dynamic viscosity of nanofluids, specifically Polyalpha-Olefin-hexagonal boron nitride (PAO-hBN) using machine learning models. The primary goal of this research is to assess and contrast ...
Hybrid fuzzy sliding mode for stick-slip suppression in drill string systems
(
Korean Society of Mechanical Engineers
, 2022 , Article)
Stick-slip vibration is one of the main factors that contribute greatly to reducing the service life of drill string equipment and decreasing the efficiency of the overall drilling system. Thus, it would be very desirable ...
Review of innovative approaches of thermo-mechanical refrigeration systems using low grade heat
(
Hindawi
, 2020 , Article)
Cooling and refrigeration systems consume around 17% of the world-wide electricity. Enhancing the performance of these systems, using renewable energy resources and waste heat recovered from industrial processes, will lead ...
Optimal design of hybrid renewable energy systems in buildings with low to high renewable energy ratio
(
Elsevier Ltd
, 2015 , Article)
We develop a simulation-based meta-heuristic approach that determines the optimal size of a hybrid renewable energy system for residential buildings. This multi-objective optimization problem requires the advancement of a ...
A hybrid optimization-simulation approach for robust weekly aircraft routing and retiming
(
Elsevier Ltd
, 2017 , Article)
We address the robust weekly aircraft routing and retiming problem, which requires determining weekly schedules for a heterogeneous fleet that maximizes the aircraft on-time performance, minimizes the total delay, and ...
Dynamic aggregated building electricity load modeling and simulation
(
Elsevier B.V.
, 2014 , Article)
In order to support the growing interest in demand response modeling and analysis, there is a need for physical-based building load models. This work presents a new approach for simulating electrical power flow in buildings. ...
Multi-objective optimal design of hybrid renewable energy systems using PSO-simulation based approach
(
Elsevier Ltd
, 2014 , Article)
Recently, the increasing energy demand has caused dramatic consumption of fossil fuels and unavoidable raising energy prices. Moreover, environmental effect of fossil fuel led to the need of using renewable energy (RE) to ...
Evaluation of a novel greenhouse design for reduced cooling loads during the hot season in subtropical regions
(
Elsevier Ltd
, 2019 , Article)
Greenhouses provide an optimized growth environment for plants. However, providing this environment is energy intensive. In subtropical regions, most of this energy is to cater for the required cooling. The cooling demand ...
