Effects of Geometric Parameters for Wavy Finned-tube Heat Exchanger in Turbulent Flow: a Cfd Modeling

In this study, the effects of thermal and hydraulic characteristics of wavy fin and tube heat exchanger are investigated. Simulation has been carried out by a commercial computational fluid dynamics code, ANSYS CFX12.0. The main objective of this study is to investigate the flow characteristics in turbulent flow. Results are predicted for the turbulent flow regime (2100≤Re≤7000) and compared wi...

10K Pulse Tube Cooler

A 3-stage pulse tube cooler has been designed to operate at 10¶K. The staged cooler uses the same compressor and parallel staging configuration for the 1 st and 2 nd stages as previously employed for our delivered High Capacity Cryocooler (HCC). The 2 nd and 3 rd stages are in a serial configuration. The addition of the third stage extends the performance of this cooler to lower operating tempe...

Selection of Capillary Tube for Refrigeration System

Proper selection of capillary tube it is essential to study the effect of capillary tube geometry on the performance of refrigeration systems. The literature review is focused on the influence of geometrical parameters like tube length, diameter, coil pitch, number of twist and twisted angle on pressure drop and coefficient of performance (COP) of the system. These parameters can be optimized u...

Effect of Surface Roughness on Vortex Length and Efficiency of Gas-oil Cyclones through CFD Modelling

Separation of suspended droplets in a fluid flow has been a great concern for scientists and technologists. In the current study, the effect of the surface roughness on flow field and the performance of a gas-oil cyclone is studied numerically. The droplets and the turbulent airflow inside the cyclone are considered to be the discrete and continuous phases respectively. The Reynolds stress mode...

Advanced Analysis of Dew Point Control Unit of Hybrid Refrigeration Systems in Gas Refineries

In this paper, an advanced analysis of a novel hybrid compression-absorption refrigeration system (HCARS) for natural gas dew point control unit in a gas refinery is presented. This unit separates the heavy hydrocarbon molecules in the natural gas, which is traditionally carried out by natural gas cooling in a compression refrigeration cycle (CRS). The power input required for the refrigeration...
