Flow Phenomena Of Laminar Split-oil Flow In A Curved Horizontal Channel

A curved, rectangular channel fed with lube oil was installed in the cylinder wall of an air cooled internal combustion engine. Inlet oil-flow is initially split into two asymmetrically curved branches. Different channel geometri- cal aspect ratios were used to determine flow pattern especially in t...

Summary:A curved, rectangular channel fed with lube oil was installed in the cylinder wall of an air cooled internal combustion engine. Inlet oil-flow is initially split into two asymmetrically curved branches. Different channel geometri- cal aspect ratios were used to determine flow pattern especially in the entry region of the channel. Results have shown pronunced influence of oil viscos- ity on the reverse flow in both channel branches. INTRODUCTION Due to different thermal loads of the engine cylinder with peak value in the vicinity of the exhaust channel, there is pronouced asymmetric circumferen- tial temperature distribution in the cylinder wall. This temperature ovalty can be
