Two phase flow distribution and the flow stability are substantial problems in designing heat exchangers with parallel-channel system. Fundamental experiment was conducted with air-water mixture in parallel-channels jointed sinuously in series. The observed flow-mal-distribution was serious at low volumetric fluxes of air and water. An installation of compressible volume upstream the mixing section brought about significant oscillation in the flow and pressure drop, mainly in the upper flow section. This oscillation was well-known pressure drop oscillation induced by dynamic interaction between negative resistance and the compressible capacity.
