CFD analysis predicts the coverage of lubricating mud over the cutting surfaces of a drill bit. The results show a maldistribution of mud that causes uneven wear on the drill bit, thus shortening its life. These predictions are borne out by the actual worn drill bits, which exhibit a very similar wear pattern. These results inform new designs which can be tested with further CFD simulations before being manufactured.
