Radiator Characterization & Testing

UT24 FSAE Vehicle - First Comprehensive Radiator Testing in UTFR History

Project Overview

To support the 2024 cooling system optimization, I designed and built UTFR's first comprehensive radiator characterization test bench. This pioneering experimental setup allowed us to gather critical thermal performance data that informed our CFD models and cooling system design decisions. The project marked a significant advancement in our team's experimental capabilities and data-driven engineering approach.

Test Bench Development

The characterization setup was designed to accurately measure radiator heat transfer performance under controlled conditions:

  • Controlled Environment: Isolated testing chamber to minimize external thermal influences
  • Precise Measurements: Multiple thermocouples and flow sensors for comprehensive data collection
  • Variable Conditions: Adjustable airflow rates and coolant temperatures to simulate real operating conditions
  • Data Acquisition: Custom circuit board for synchronized sensor data collection

Custom Circuit Board Design

I designed and fabricated a custom data acquisition circuit board specifically for this testing, similar to the drivetrain datalogger system:

Multi-Sensor Integration

Integrated thermocouples, flow meters, pressure sensors, and fan speed controls into a single acquisition system

Real-Time Data Processing

High-frequency data sampling with onboard processing for immediate validation and system control

Analytical Validation

In addition to experimental testing, I developed analytical calculations in Excel to validate and correlate the experimental results:

  • Heat transfer coefficient calculations based on fundamental thermal principles
  • NTU-effectiveness method for heat exchanger performance prediction
  • Correlation between experimental data and analytical predictions

Experimental Results & Data Collection

The comprehensive testing campaign generated valuable performance data across multiple operating conditions:
