. Joule heating effect on the thermal equation is retained. Analytic solutions for stream function and temperature are constructed. Numerical integration is carried out for pressure rise per wavelength. Effects of influential flow parameters have been pointed out through graphs.Key words:peristaltic flow; convective conditions; Joule heating......
to 170 °C in 50 min with a heating rate of 3.06 °C/min. These experiment results showed that the spent automobile catalyst was a medium loss material. On the other hand, the temperature rise curve was gradually away from the tangent of point (4 min, 35 °C) with the increase of time, indicating that the heating rate was decreased. According to the heat conduction equation: ρc(T/t)= ......
Development of inclusions in 3104 alloy melt during heating and holding treatmentsXiao-xiong Luo1,2,Hai-tao Zhang1,Xing Han1,Shi-jie Guo3,Jian-zhong Cui1,Hiromi Nagaumi31. Key Laboratory... typical inclusions in 3104 alloy melt were described during heating and holding processing. The settling process of inclusion particles was investigated by measuring the contents of inclusions......

]. However, conventional calcination has the disadvantages of slow heating rate, high energy consumption, and uneven heating inside and outside the material. Therefore, it is essential to seek an alternative...×75 mm to heat with microwave nor conventional field. The thermal treatment of the kaolin was carried out in a laboratory muffle furnace at a heating rate of 10 °C/min in air, and heated in the range......
