Finite volume calculation method for solidification heat transfer of irregular-section continuous casting billet

The invention designs a finite volume calculation method for solidification heat transfer of a continuous casting billet with an irregular section. Firstly, a 1/2 continuous casting billet simulation calculation domain is constructed according to the section size of the irregular section continuous casting billet; dividing an unstructured grid in the established 1/2 continuous casting billet simulation calculation domain, and storing grid information; secondly, establishing a non-structural finite volume heat transfer model aiming at the problem of continuous casting solidification heat transfer of the continuous casting billet; and finally, simulating the solidification heat transfer phenomenon of the irregular continuous casting billet in the continuous casting process by utilizing the established non-structural finite volume heat transfer model. A volumetric method is adopted for calculation, and compared with a finite element method, the calculation rate is improved; proper boundary conditions are selecte
