Nano Fluid in Heat Source Channel Mixture Multiphase CFD Simulation

This CFD simulation training explores the behavior of nanofluid in a heat source channel using ANSYS Fluent’s Mixture multiphase model. The focus is on simulating the flow and heat transfer characteristics of a nanofluid mixture, consisting of a base fluid and nanoparticles, in a channel with a heat source.

Key aspects of this simulation include:

Mixture Multiphase Model Setup: Configuring the Mixture model for the nanofluid system. The base fluid is defined as the primary continuous phase, and the nanoparticles as the secondary dispersed phase.

Simulation Domain: Utilizing a pre-defined channel geometry with an integrated heat source.

Phase Properties: Defining the properties of both the base fluid and nanoparticles, including density, specific heat, and thermal conductivity.

Mixture Properties: Calculating effective properties of the nanofluid mixture based on the volume fraction of nanoparticles.

Heat Transfer Modeling: Implementing energy equations to capture heat transfer from the source to the nanofluid mixture.

Boundary Conditions: Setting up inlet, outlet, and wall conditions, including the heat source specifications.

Turbulence Modeling: Selecting and configuring an appropriate turbulence model for the nanofluid flow.

Post-processing and Analysis: Examining temperature distributions, velocity profiles, nanoparticle concentration patterns, and heat transfer coefficients along the channel.

This simulation provides insights into the enhanced heat transfer characteristics of nanofluids in channels with heat sources, with applications in cooling systems and heat exchangers. Participants will gain skills in applying the Mixture multiphase model to simulate nanofluid behavior, focusing on the combined flow and heat transfer aspects in a practical engineering context.
