The significance of solar energy has recently diverted the attention of researchers; this is due to the experimental or the numerical analyises of solar energy and lack of fractional analytic approaches. This manuscript is communicated to model the problem of the enhancement of heat transfer...

The economic and financial chaos caused by COVID-19 has been a discussion topic since the beginning of 2020. This study intends to provide a parallel comparison of volatility change and external shock persistence of the Islamic and conventional stock indexes of the Pakistan Stock Exchange. The...

In this letter, energy transfer of Jeffery-Hamel nanofluid flow in non-parallel walls is investigated analytically using Galerkin method. The effective thermal conductivity and viscosity of nanofluid are calculated by the Maxwell-Garnetts (MG) and Brinkman models, respectively. The influence of...

Aerodynamic drag in a bicycle can originate through the rotation of wheels, and the addition of cladding on the wheels has a pronounced impact on the same. In the present work, the effect of cladding on the wheels of a bicycle is studied in terms of the percentage cladding in order to predict...

Air conditioning systems accountable a huge amount of energy consumption, the purpose of this work is to inspect the energy efficiency and the economic impact for air-conditioners using Wireless Sensing and Actuator Networks. Different methods are explored. Referring to ASHRAE Standard 62.1-2007...

In this study, gas and steam bottoming cycles, driven by the exhaust gas of Gas turbine cycle, are analyzed thermodynamically. The waste heat of the Gas turbine topping cycle (GT) exhaust gas is used partially to heat the air in the air bottoming cycle and partially to generate steam by passing...

The search for an engine cycle with high efficiency, multi-sources of energy and less pollution has led to reconsideration of the Stirling cycle. Several engine prototypes were designed but their performances remain relatively weak when compared with other types of combustion engines. In order...

To increase the performance of Stirling engines and analyze their operations, a second-order Stirling model, which includes thermal losses, has been developed and used to optimize the performance and design parameters of the engine. This model has been tested using the experimental data obtained...
