Effect of ethanol addition on flame characteristics of waste oil biodiesel

Chaotic Diagnostics in a Biodiesel Combustion System Using PLIF and Nonlinear Time Series Analysis▴

“…Using the flame image to extract the flame combustion information and to analyze the data of the combustion information, the influence of initial conditions on the combustion process can be studied. Through data analysis of combustion process information, the combustion state can be accurately identified and classified, thus providing useful judgment strategies and accurate prediction for industrial production [19]. For many years, researchers have characterized the properties of chaotic behaviors and distinguished between the different types of chaos by plenty of methods and criterias, including power spectrum [20,21], features of a trajectory in the phase space such as strange attractor [22], Lorenz map [23], Poincare map [24], Hurst index [25,26] and Lyapunov stability [27,28].…”

Visualization Research of Nonpremixed Biodiesel/Air Jet Flames Unstable Combustion Process▴

“…Combustion plays an important role in the fields of energy engineering, power industry, chemical industry, metallurgy, etc., and combustion performance can directly influence the safety and economy of the productive activity [1,2]. Its performance can be accurately gained in time, and is of important significance, in order to provide the basis for equipment control, improve combustion efficiency [3], and to accomplish a stable work of the system. Combustion monitoring should not only be able to display data and image, but it should also be a continuous online auto‐monitoring in the combustion process.…”
