This study uses ANSYS Polyflow to analyze the relationship between speed, temperature, and pressure. A wheat flour’s viscosity, thermal conductivity, and heat capacity were found to be 12,000 cps, 0.375 W/m-K, and 2190 J/kg-K, respectively. The speed was increased from 5 to 100 RPM in five-step incr...
