Air Conditioning of a Room with Heat Source CFD Simulation

This project focuses on the CFD simulation and analysis of air conditioning in a room containing a significant heat source using ANSYS Fluent. The primary emphasis is on understanding the interaction between the air conditioning system and the heat source in a specific case study, and how this affects temperature distribution and air circulation patterns within the space.

Project Objectives:

Simulate the thermal dynamics of a room with an air conditioning system and a prominent heat source for a specific case study.
Analyze the impact of the heat source on temperature distribution and airflow patterns.
Evaluate the effectiveness of the air conditioning system in maintaining comfort levels in the presence of the heat source.
Gain proficiency in using ANSYS Fluent for indoor thermal environment simulations.
Training Outline:

Introduction to ANSYS Fluent setup for the room air conditioning case study with a heat source.
Defining boundary conditions for the air conditioning inlets/outlets and the specific heat source.
Implementing appropriate turbulence models for indoor air flow simulations.
Configuring thermal radiation models to account for the heat source’s impact.
Running steady-state and transient simulations to capture the room’s thermal behavior.
