Abstract:Multi-hole orifices (MOs) is a promising throttle device applying in refrigeration system or plant.The geometric description of multi-hole orifices (MOs) is more complex than single-hole orifices (SOs). The flow control characteristics and structural system of MOs need to be investigated. This paper presents a comprehensive geometric description for MOs by a series of throttle experiments. This paper first defines a comprehensive set of geometric architectures involving orifice arrangement criteria and three geometric parameters, then investigates the effect of various geometric features on the pressure loss characteristics of MOs by throttle tests, finally develops practical models to evaluate the pressure loss coefficient of MOs. The presented structural system of MOs including orifice arrangement criteria, geometric parameters and throttle models, provides convenient conditions for structural design and manufacturing for MOs.
