An analytical method for the solution of two phase Stefan problem in cylindrical geometry
Khalid, Muhammad Zeeshan; Zubair, Muhammad; Ali, Majid (Journal article; Peer reviewed, 2019)Two phase Stefan problem was solved using analytical method in cylindrical domain. To solve governing equations Eigen conditions were formulated by using separation of variable technique. Eigenvalues of the eigencondition ... -
Catalytic Oxidation of NO over LaCo1−xBxO3 (B = Mn, Ni) Perovskites for Nitric Acid Production
Salman, Ata ul Rauf; Hyrve, Signe Marit; Regli, Samuel K.; Zubair, Muhammad; Enger, Bjørn Christian; Lødeng, Rune; waller, david; Rønning, Magnus (Journal article; Peer reviewed, 2019)Abstract Nitric acid (HNO3) is an important building block in the chemical industry. Industrial production takes place via the Ostwald process, where oxidation of NO to NO2 is one of the three chemical steps. The reaction ... -
