dc.description.abstract | Impinging jets are known as a method of achieving high convective heat transfer
coefficients. One potential application of impinging jet heat transfer is the air jet cooling of a
grinding process. A grinding process generates heat that must be dissipated to avoid thermal
damage. To date, this has been achieved using flood cooling with a traditional coolant such
as an oil and water mixture; however, using a jet of air in its place has obvious environmental
and economic benefits. For a range of grinding test configurations, results are presented of
the convective heat transfer from the workpiece, along the notional plane of cut, and of the
air flow velocity in a two-dimensional plane perpendicular to the workpiece. It has been
shown that a boundary layer that develops around the rotating grinding wheel has the effect
of displacing a peak in the distribution of the local heat transfer coefficient from the notional
arc of cut. To effectively cool the grinding zone, therefore, it is necessary to penetrate this
boundary layer and this can only be achieved when the jet velocity is substantially greater
than the tangential velocity of the wheel. | en |
