Aiming at the problem that eccentricity of casing in circular hole happened in thermal well,the finite element model is established and the effect of casing eccentricity on wellbore temperature field,casing stress and displacement were analyzed.

Study on soft-contact electromagnetic continuous casting of hollow billet;

5%Pb hollow billet under traveling magnetic field.

Distribution of magnetic field in electromagnetic continuous casting process of Al-alloy hollow billets is studied by way of numerical simulation.

In this paper,through the CFD modeling of the ash-agglomerated fluidized bed gasifier,the gas molar concentration distributions in the bed with the influences of the oxygen flow rate from the central nozzle,the steam flow rate from the distributor and the pressure of the bed are studied.

Control of macrostructure and surface quality during electromagnetic continuous casting of Sn-Pb hollow billets;

Based on the solidification characters of hollow billets, a mathematical model was established to study numerically heat transfer during horizontal continuous casting of BFe30-1-1 alloy.

In order to obtain hollow billets of BFe30-1-1 alloy, a new casting technology was investigated and hollow billets with size of φ83 mm×20 mm were produced in laboratory.
