REYNOLDS STRESS BUDGET IN THE OUTWASH JET ARISING FROM COLLIDING CURVED WALL JETS

Abstract

Various Reynolds stress budgets in an outwash jet resulting from the collision of two curved wall jets are experimentally investigated. The outwash jet is initially accelerating until the two detached jets become fully merged. Later, the merged jet develops to obtain similarity. The Reynolds stress budgets in the interacting region (where the jet is accelerating) and those in the similar region have been carefully evaluated on the basis of measurements with hot-wire anemometry. The reported budgets include the kinetic energy budget, the longitudinal normal stress budget, the lateral normal stress budget, and the shear stress budget, which are rarely found elsewhere.
