HEAT EXCHANGER DESIGN CHALLENGE
The Tale of the Hidden Heat: A Heat exchanger design challenge for Heroes
In the heart of a bustling textile factory, a silent crisis unfolds every day. Thousands of liters of hot wastewater flow out, its precious energy slipping away—wasted. Freshwater, meanwhile, demands to be heated—rising from a mere 22°C to a productive 50°C—adding costs, energy burdens, and inefficiencies.
For years, the solution seemed just out of reach, ready to slip into the hands of multinational manufacturing giants in the international market. But we refused to let it go. Instead, we took a bold step—to craft this product manually and inspire our local students to design a world-class solution for real-world applications. This is more than a challenge—it’s a movement, and you are part of it.
The Challenge
Design and simulate a high-efficiency SS316 heat exchanger to:
- Heat 30 m³/h of freshwater (22°C → 50°C) using 120 m³/h wastewater at 70°C.
- Account for 5% filtration loss and friction head losses.
- Design and size pumps for both fluids to ensure smooth and efficient flow.
- Consider practical fabrication constraints in your design layout to make it real and implementable.
This isn’t just about efficiency. It’s about proving that local ingenuity can solve global problems.
Who Can Join?
- You can participate individually or in a team of up to 3 members.
- All participants must be currently studying at MIST in any level.
Your Mission
- Submit the following deliverables via email to: rabby@me.mist.ac.bd
- Detailed Assembly Design Layout: Think fabrication-ready! Every aspect must be practical, clearly defined, dimensioned, and innovative.
- Simulation Files: Show heat transfer efficiency, temperature distribution, and flow dynamics.
- Heat Exchanger Specifications:
- Tube material: SS316
- Tube diameter, thickness, length, and number of tubes.
- Pump Design Calculations: Specify the required flow rate and head.
- Performance Report: Include heat transfer rate, LMTD, total heat transfer area, and impact of filtration loss.
Judging Criteria
The heroes of this challenge will be judged on:
- Thermal Efficiency: Maximize the heat recovery.
- Pump Optimization: Precision in sizing the pumps for flawless performance.
- Innovation: Unique, practical approaches to design and fabrication.
- Real-World Feasibility: Designs that can truly be implemented.
