Greenhouse gas reduction potential by producing electricity from biogas engine wate heat using organic Rankine cycle
(Elsevier, 2016)
Organic Rankine cycles have been identified as a suitable technological option for converting low-grade heat into electricity with relatively high efficiency, and the organic Rankine cycle technology has been successfully ...
Centrifugal Compressor efficiency improvements and its environmental impact in waste water treatment
(Elsevier, 2015)
Energy costs typically dominate the life-cycle costs of centrifugal compressors used in various industrial and municipal processes, making the compressor an attractive target for energy efficiency improvements. This study ...
Modelling of Low-Reynolds-Number Centrifugal Compressors: Challenges in Performance and Flow Control Prediction
(2018)
A low-Reynolds-number causes a performance deterioration in centrifugal compressors due to the relative increase in boundary layer thickness, tip clearance, and surface roughness. The degradation of the efficiency can be ...
Validation of the Axial Thrust Estimation Method for Radial Turbomachines
(Hindawi, 2021-02-24)
The fast preliminary design and safe operation of turbomachines require a simple and accurate prediction of axial thrust. An underestimation of these forces may result in undersized bearings that can easily overload and ...
Numerical analysis of working fluids for large scale centrifugal compressor driven cascade heat pumps upgrading waste heat
(Elsevier, 2020-05-14)
Heat pump technology has the capability to upgrade unusable low-temperature waste heat and make the upgraded heat usable for different types of industrial and domestic heating applications. Heat upgrading could allow to ...
Effect of non-ideally manufactured riblets on airfoil and wind turbine performance
(Elsevier, 2020-03-25)
Riblets are a passive flow control method, which can be used for drag reduction, especially with small wind turbines that have a low Reynolds number. Riblet manufacturing, however, is a challenging task and the required ...
