摘要:
A measurement of normal stress differences in a shearing elastic liquid is accomplished through direct measurement of hole pressure. Gravity flow down an inclined channel is used and hole pressure is measured for slots perpendicular and parallel to the flow, as well as for a circular hole. The first and second normal stress differences are calculated under the assumption of second‐order fluid behavior. Dynamic data are compared and a discrepancy noted.
