CFD Simulation on The Effect of Impeller Immersion Depth and Impeller Rotational Speed on The Flow Pattern and Temperature Drop of Molten Ferronickel During Desulphurization Process

Autor: Rizqy Muhammad Fatih Ar, Hidayat Taufiq, Santoso Imam, Santoso Ramadhani

Publikováno v: E3S Web of Conferences, Vol 543, p 02005 (2024)

Desulphurization is the purifying process of molten ferronickel from sulphur impurity. During the desulphurization process using a ladle furnace equipped with an impeller, the fluid flow characteristics and the temperature drop of molten ferronickel

Studying the Equilibrium Points of the Modified Circular Restricted Three-Body Problem: the Case of Sun-Haumea System

Autor: Huda, Ibnu Nurul, Dermawan, Budi, Saputra, Muhammad Bayu, Sadikin, Rifki, Hidayat, Taufiq

We intend to study a modified version of the planar Circular Restricted Three-Body Problem (CRTBP) by incorporating several perturbing parameters. We consider the bigger primary as an oblate spheroid and emitting radiation while the small primary has
