21Design and Simulation Study on Busduct System in the Prediction of Temperature Variation Using CFD

Busduct systems are key components in industrial and commercial power distribution, but their thermal performance often limits reliability and safety. Excessive heating in busducts due to high currents, poor ventilation, and suboptimal materials can lead to failures. This paper presents a 3D CFD model to predict temperature variation in busducts under different operating and design scenarios. Variants such as material selection, airflow (forced/free), vent geometry, and insulation are simulated. The study also applies TRIZ (Theory of Inventive Problem Solving) methods to guide design improvements. Results reveal critical hotspots, temperature gradients, and the influence of copper and aluminium busbars under air velocities of 10 m/s and 20 m/s. Forced convection significantly reduces peak temperatures, while copper shows superior thermal performance.The work can help in optimizing busduct design for better energy efficiency, safety, and lifetime.
