Temperature distributions along the central axis of the cylindrical samples are heating in different hydrodynamic conditions are measured. It is shown that concentrated axial flow around sample leads to ver- tical gradient of the heating temperature, which depends on the temperature value, sample size and electro- lyte flow rate. It is proposed the method of the temperature gradient decreasing up to 0.8–3°C/mm by the distributed axial and radial flow around sample.
