To evaluate how heat exchanger geometry, heating power, and stirring speed influence heat transfer efficiency when mixing water compared to a water and food waste slurry.
Tested jacketed insulation tanks and internal helical coils using a propeller agitator under varying heating power and stirring speeds.
Determined overall heat transfer coefficients and thermal resistance via a transient method that tracked time-dependent temperature changes and solved unsteady enthalpy balances.
The introduction of food waste decreased the heat rate of the agitated fluid by an average of 18.13% in jacket heat exchangers.
Food waste reduced the heat rate by an average of 49.51% in helical coil heat exchangers, with accumulated solid fouling further impeding heat transfer.

Implication

Experimental study reveals that food waste slashes heat transfer rates in agitated vessels by up to 49.51%, indicating that solid fouling significantly impairs thermal efficiency in bioreactors.
