Firehose CFD Simulation

This module introduces mechanical engineering students to Computational Fluid Dynamics (CFD) analysis of a firehose using ANSYS Fluent, focusing on fluid flow characteristics in firefighting applications.

Key aspects covered:

Introduction to fluid dynamics principles relevant to firefighting equipment
Importing a pre-made mesh of a firehose into ANSYS Fluent
Setting up boundary conditions to simulate water flow through the firehose
Configuring ANSYS Fluent for internal flow simulation in a flexible hose
Running the simulation to analyze water flow behavior
Visualizing flow patterns within the firehose, including velocity streamlines and pressure contours
Analyzing pressure distribution and velocity profiles along the hose length
Examining the water jet characteristics at the hose exit
Introduction to concepts such as pressure loss in flexible pipes and jet formation
Basic interpretation of results to understand firehose performance

This tutorial provides practical experience in using ANSYS Fluent for fluid flow analysis in firefighting equipment. Learners will gain insights into how water behaves as it flows through a firehose, including factors affecting flow rate, pressure, and jet characteristics. The module emphasizes the application of CFD in analyzing real-world mechanical engineering problems, particularly in the context of firefighting technology. This knowledge can be applied to improve the efficiency and effectiveness of firefighting equipment and techniques.
