Effects of homogeneous-heterogeneous reactions in flow of Powell-Eyring fluidT. Hayat1, 2, M. Imtiaz1, A. Alsaedi2(1. Department of Mathematics, Quaid-I-Azam University 45320, Islamabad 44000... is investigated. The flow is caused by a stretching surface with homogeneous-heterogeneous reactions. The governing nonlinear differential equations are reduced to the ordinary differential equations......

, China) Abstract: The TG-DSC curves were tested to study the nitrided ferrovanadium preparation reaction processes, and the kinetic parameters of the relevant reactions were calculated using Coats-Redfern method. The results show that C can react with V2O5 obviously at around 670 ℃. However, the carbonation reactions occurs when the temperature is higher than 1 000 ℃ and the nitridation reactions......
