Heat transfer and power measurements in stirred tanks using heat flow calorimetry

A new method is presented for determining the power consumption of an impeller in a stirred tank as well as the inside film heat transfer coefficient. Five working fluids were used. Power consumptions for turbine, Pfaudler and anchor impellers agree well with literature values. Heat transfer coefficie A plant-scale heat transfer coefficient can be estimated rapidly and accurately from a few runs in a bench-scale heat flow calorimeter, without having
