Lubricant flow through the nozzle of a drawing die

Lubricant flow through the nozzle of a drawing die, governed by the power-law rheological equation of state, is examined. The nozzle dimensions, ensuring a maximum lubricant throughput, are obtained analytically by using the variation methods. A study is undertaken of the effects of the rheological...

Description
Summary:Lubricant flow through the nozzle of a drawing die, governed by the power-law rheological equation of state, is examined. The nozzle dimensions, ensuring a maximum lubricant throughput, are obtained analytically by using the variation methods. A study is undertaken of the effects of the rheological equation exponent and piezocoefficient on the film thickness, heat generation and pressure distribution over the nozzle length.
