Method for extracting light stripes of wheel profiles from consecutive frames in complex background by LEI Yongwei, LEI Lei, SONG Dongli, LIN Hanxiao

“…Additionally, an algorithm of edge expansion in consecutive frames utilized the similarity between image frames to segment light stripes, contributing to the algorithm’s robustness against texture changes on object surface. While maintaining stability, the proposed method achieved an image detection speed 16 times higher than that of single-frame processing methods, meeting the real-time requirements for wheelset profile detection, with an average processing time per frame of 0.22 s.…”

Comparison Between Model-established Simulation and Experiment for Evaporators by Yin Bin, Ding Guoliang, Ouyang Ti

“…The simulation on an evaporator of an R134a air-conditioning unit was conducted with a steady state distribution parameter model.Using the update Kattan model,R134a flow patterns inside smooth tubes were divided, and then the flow pattern map was obtained.Based on the flow pattern map,local boiling heat transfer coefficients were calculated with different correlations.The surface heat transfer coefficient and the pressure drop of louver fin evaporators were calculated with C C Wang's model.The moisture separation coefficient was determined from the database established with test data.During simulation,implicit cubic polynomial curve-fitting model was used to calculate R134a thermodynamic properties.The results show that the simulation values are in agreement with the experiment data.The average relative error of refrigeration capacity,dry bulb temperature of outlet air,and R134a outlet temperature is 1.12%,1.25%,and 4.0%,respectively.Moreover,the maximum relative error of outlet-air enthalpy is 0.88%.…”
