Cattaneo-Christov heat flux and entropy generation on hybrid nanofluid flow in a nozzle of rocket engine with melting heat transfer

Climate change remains one of the world’s significant threats today, and thus Sustainable Development Goal (SDG) 13 prioritizes countries to reduce global greenhouse gas emissions and mitigate climate change by 2030. Recent studies have scrutinized the impact of Information and Communications Technologies (ICTs) on the environment. However, the majority of these studies assumed that the environmental impact of ICT is homogenous across countries. This study, therefore, investigated the impact of ICT on environmental degradation, considering the difference in ICT quality among countries. Applying a panel dataset of 110 countries between 2000 to 2018 and the instrumental variable generalized method of moments (IV-GMM) technique, the findings revealed that ICTs improve environmental sustainability in countries with high ICT quality while degrading the environment in countries with moderate and low ICT quality. The results of the causality analysis also showed bi-directional causality between ICT and carbon emissions in countries with high and moderate ICT quality, while there is a uni-directional causality running from carbon emissions to ICT in countries with low ICT quality. Policies that enhance ICT usage through low pricing were recommended for moderate and low ICT quality countries to help mitigate environmental degradation.

“…Non-Newtonian fluids play a significant character in many designs and building processes, including food processing, gas exploration, and physical and biochemical treatment. Previously, plasma was considered to be a Newtonian fluid [2,3], but Thurston [4] explained that plasticity is a fundamental property of rheological blood, meaning that human blood is non-Newtonian due to the viscoelastic efficiency of blood cells. Many non-Newtonian tissues, such as fluid, are considered blood.…”

The effects of nanofluid radiation and magnetic fields are important in biotechnology and medical treatment. The efficiency of hybrid nanomaterials flow (Carreau fluid) over a porous medium was investigated, and the findings were presented. The partial slip impact was used to thoroughly scrutinize the properties of the nanofluid flow. Using suitable variables, the PDEs in the Carreau model were reduced to ODEs, and the governing PDEs were transformed to ODEs using similarity transformations. The consequent ODEs are numerically investigated using the RKF‐45 Method. Furthermore, the results of the parameters involved in thermal and velocity were discussed. To the finest of the journalists' knowledge, no one has endeavored to depict medical occurrences and medical approaches by watching the flow through a malleable porous medium including blood as a base fluid and hybrid nanostructure materials. Indeed, the endeavors of this study are exceptional, and the obtained simulations have never been published by anyone academic.

“…Several scholars have recently added to this intriguing phenomenon, as seen in Refs. [27][28][29][30][31][32][33][34][35][36][37][38] The goal of this research is to look the aspects of Bioconvectional flow viscoelastic nanofluid and Solutal boundary conditions using a wedge. Here we discussed the significance of three cases of wedge like as (shrinking a = 0:5, static a = 0:0, and stretching a = 0:5).…”

Nanofluid suspension comprises a chip-sized rigid particle trapped in the convection fluid. These forms of fluids are known as nanofluids. Nanofluid is more user-friendly in engineering including fuel cells, cooling systems, and a wide range of applications of technologies to improve. The idea of this work is to analyze the Bio convectional stream characteristics and Solutal boundary characteristics of nanofluid flow via a wedge. Furthermore, the consequences of motile bacteria and heat conductivity are considered. When the boundary layer is estimated, the governing equations will be seen. Coupled PDEs are reduced into nonlinear ODEs using the required similarity vector, and the resultant structures are shown using the MATLAB computational tool bvp4c firing (Labotto IIIA formula). The implications of fluid velocity, temperature area, nanoparticles concentration, and microorganism concentration on the induced parameters are shown in graphical and numerical values. The velocity field is booming up for higher fluid parameter values and depressed for larger buoyancy ratio parameter estimations. For increasing levels of both the thermal conductivity parameter and the thermal Biot number, the temperature field rises. The microorganism’s field has dropped for Peclet number values and increased for Microorganisms Biot number values. The concentration field is lowered for the Lewis number while it is increased for the concentration Biot number. The current implications are novel and original for the investigation of flow and heat transfer over a wedge in a viscoelastic nanofluid with thermal conductivity, motile microorganisms, and bioconvection.
