Carbon Capture and Storage (CCS) is a promising technology that stops the release of CO2 from industrial processes such as electrical power generation. Accurate measurement of CO2 flows in a CCS system where CO2 flow is a gas, liquid, or gas-liquid two-phase mixture is essential for the fiscal purpose and potential leakage detection. This paper presents a novel method based on Coriolis mass flowmeters...
Flowrate is one of the significant parameters in energy and resource engineering. This paper presents a multi-sensor insertion flow measurement system and a flow measurement method that includes an integration procedure based on cubic B-spline interpolation. The flow field around measuring section at different straight pipe length in circular conduit was simulated by FLUENT software and a comparative...
The energy conversion efficiency is decreased by the high inertia of large-scale wind turbine generation system (WTGS). A novel maximum power point tracking (MPPT) algorithm was proposed in this paper to enhance the efficiency. The algorithm was derived from conventional optimum torque control (OTC) MPPT strategy using gradient approximation. To qualify the stability and dynamic performance, a small...
This paper presents a novel method for the real-time apparent density measurement of the working fluid in outlet pipes of a stream-injection boiler. The measurement system consists of a vertical measuring pipe, a container with constant height and a differential pressure (DP) transmitter. The working fluid in the upper part of the vertical measuring section flows into the container which is connected...
The performance of HMM-based text to speech (TTS) system is affected by the basic modeling units and the size of training data. This paper compares two HMM based Mandarin TTS systems using syllable and phone as basic units respectively with 1000, 3000 and 5000 sentences' training data. Two female speakers' corpora are used as training data for evaluation. For both corpora, the system using syllable...
The performance of the cold end temperature compensation for the thermal couple was investigated. The cold end temperature compensation errors of two typical thermocouples were calculated point by point, based on that the error tables were arranged in order to visually display the defect of the conventional compensation. The bi-bridge of the compensation solution was recommended in the paper as contrast...
The device was developed to accurately measure the Concentration of pulverized coal in the pneumatic conveying pipe. The sensor assembly was composed of gamma-ray source, tube of the sensor, ionization chamber fill with inert gas electrometer and lead cannon tube shield. The gamma point source was fixed at the cross-section centre of the pipe, the collimation exit portal was vertical to the axis line...
