On the basis accepted and critically clarified assumptions, a non–linear and afterwards linearized mathematical model of fuel oil cooling chamber has been developed in engineering sense sufficiently correct. The model is in the form of set of partial differential equations with constant coefficients. Using the appropriate numerical simulation of the results derived, the dynamic of this process has been shown in the form of appropriate transient processes responses which quite well correspond to the real process behavior.

De Algorithm

Optical fiber F-P sensor has several advantages, such as strong anti-interference ability, quick speed and high precision. It is widely applied in detecting fields. But optical fiber F-P sensor deviates from working point easily in practical applications, it leads to output signal attenuation and the decreasing of signal noise ratio. The double wavelength optical fiber F-P sensing system is designed to solve the problem. DE algorithm mathematical model of sensing system is established, meanwhile, a higher orthogonal precision sensing system is optimization designed. The orthogonal error of sensing system is studied. The results show that DE algorithm is correct and reliable. Its run time is shorter and the error is less than 10-3. The optimization objective decreases sharply. When the length of F-P cavity changes 0~2500nm, the orthogonal error of sensing system is less than 5%. It has higher stability and anti-interference ability. These results show that the DE algorithm can be used for the structural optimization design of optical fiber F-P sensor.
