Flow Characteristics of R600a in an Adiabatic Capillary Tube

A Simulation for Predicting the Refrigerant Flow Characteristics Including Metastable Region in Non-Adiabatic Capillary Tubes

The capillary tube/suction line heat exchanger (SLHX) is widely used in small refrigeration systems. The refrigerant flowing in the SLHX experiences frictional and accelerational head losses, flashing, and heat transfer simultaneously. The simulation of refrigerant flow through SLHX is important since this will help engineers analyze and optimize the SLHX incorporated in a refrigeration system....

A Study on Capillary Tube Flow

Influence Of Oil On Flow Characteristics Through Capillary Tube In Refrigeration Cycle

A capillary tube is widely used as an expansion device for small refrigeration cycles. Recently, immiscible oil is sometimes used in the refrigeration cycle to improve severe lubricating conditions and to prevent blockage of the capillary tube caused by the hydrolysis of ester oil. This paper discusses the influence of mixing of the immiscible oil with the refrigerant on the flow characteristic...

Two-Phase Flow in a Diabatic Capillary Tube

Micro-flow separation system using an open capillary tube that works under laminar flow conditions.

A micro-flow separation system was developed using an open capillary, fused-silica or polyethylene tube, and an aqueous-organic mixture (water-acetonitrile-ethyl acetate mixture) as a carrier solution. A model analyte solution containing 2,6-naphthalenedisulfonic acid and 1-naphthol was injected into the capillary tube by a gravity method. The analyte solution was subsequently delivered through...
