"heat transfer to the anode in free burning arcs"
Used in print(Raymond C. Binder et al., editors, Proceedings...)
In free_burning electric arcs , for_instance , approximately 90 % of the total arc power is transferred to the anode giving_rise to local heat fluxes in excess of **f as measured by the authors - the exact value depending_on the arc atmosphere .
The higher heat transfer rates at the anode compared with those at the cathode can be explained by the physical_phenomena occurring in free_burning arcs .
The heat transfer to the anode in free_burning arcs is enhanced by a hot gas_jet flowing from the cathode towards the anode with velocities up **f .
Hence , the flow conditions at the anode of free_burning arcs resemble those near a stagnation point .
it is apparent from the above and from experimental evidence that the cooling requirements for the anode of free_burning arcs are large compared with those for the cathode .
