ABSTRACTA new high-pressure, high-temperature submerged impinging jet device is described. The experimental results of its flow characteristics are summarized. The device generates welldeveloped steady flow in the jet tubes with laminar flow up to Reynolds numbers (Re) of 1,980 and turbulent flow ab...
