Summary
This study analyzes magnetohydrodynamic (MHD) nanofluid flow with carbon nanotubes, focusing on entropy generation. Increased magnetic and ion-slip parameters reduce flow velocity but enhance entropy generation.
Area of Science:
- Fluid Dynamics
- Heat Transfer
- Nanotechnology
Background:
- Magnetohydrodynamics (MHD) and nanofluids are crucial for advanced heat transfer applications.
- Carbon nanotubes (CNTs) offer superior thermal conductivity, making them effective cooling agents.
- Entropy generation analysis is vital for optimizing energy systems.
Purpose of the Study:
- To investigate the entropy generation in MHD nanofluid flow between rotating plates.
- To analyze the influence of Hall current and ion-slip effects on fluid dynamics and heat transfer.
- To evaluate the role of carbon nanotubes as efficient heat transfer mediums.
Main Methods:
- Employing similarity transformations to convert partial differential equations into ordinary differential equations.
- Utilizing an optimal approach for solving the transformed equations.
- Analyzing non-dimensional physical parameters, skin friction coefficient, and Nusselt number.
Main Results:
- Increased magnetic and ion-slip parameters were found to decrease nanofluid velocity.
- Higher magnetic forces lead to a more pronounced conduction heat transfer mechanism.
- Entropy generation increases with elevated magnetic and ion-slip parameters.
Conclusions:

Hagen-Poiseuille flow describes a viscous fluid's steady, incompressible flow through a cylindrical tube with a constant radius R. This flow profile is often applied to understand fluid transport in narrow channels, such as capillaries. It serves as a foundational example of laminar flow. In this model, cylindrical coordinates (r,θ,z) are used to describe the radial (r), angular (θ), and axial (z) dimensions within the tube. For Hagen-Poiseuille flow, the velocity profile is purely axial,...

7.2K
The Joule-Thomson effect, also known as the Joule-Kelvin effect, describes the temperature change of a fluid when it is forced through a valve or porous plug while keeping it in a thermally insulated environment. This experiment is called a throttling process. This is an important effect widely used in refrigeration and the liquefaction of gases.
This experiment forces high-pressure gas through a throttle valve or a porous plug to a lower-pressure region. The gas expands as it passes through to...

Heat transfer between the human body and its environment occurs through four main mechanisms: conduction, convection, radiation, and evaporation.
Conduction, accounting for approximately 3% of body heat loss at rest, is the process of exchanging heat between molecules of two materials in direct contact. This can result in both heat loss and gain. For instance, when the body is submerged in water, which conducts heat 20 times more effectively than air, it can either lose or gain significant...

Just as interesting as the effects of heat transfer on a system are the methods by which the heat transfer occur. Whenever there is a temperature difference, heat transfer occurs. It may occur rapidly, such as through a cooking pan, or slowly, such as through the walls of a picnic ice box. So many processes involve heat transfer that it is hard to imagine a situation where no heat transfer occurs. Yet, every heat transfer takes place by only three methods: conduction, convection, and radiation.

In convection, thermal energy is carried by the large-scale flow of matter. Ocean currents and large-scale atmospheric circulation, which result from the buoyancy of warm air and water, transfer hot air from the tropics toward the poles and cold air from the poles toward the tropics. The Earth’s rotation interacts with those flows, causing the observed eastward flow of air in the temperate zones. Convection dominates heat transfer by air, and the amount of available space for the airflow...

01:22Couette Flow

Couette flow represents the flow of fluid between two parallel plates, with one plate fixed and the other moving with a constant velocity. This configuration allows for a simplified analysis using the Navier-Stokes equations, which govern fluid motion under conditions of viscosity and incompressibility. For Couette flow, the assumptions include a steady, laminar, incompressible flow with a zero-pressure gradient in the flow direction. This flow type is beneficial for understanding shear-driven...
