Objective

• Determine time required to cool ramen noodles by
  blowing

Experimentally
Analytically

Results

• Analytical
• Impinging Jet Correlation 4 seconds
• Experimental
• Thermocouple / Matlab 9 seconds
• Possible sources of error
• Lumped Capacitance
• Material properties
• Measurement / Instrumentation

5
Conclusions and Recommendations

• Blow individual spoonfuls rather than the entire
  bowl to minimize cooling time
