โœฆ Synopsis

We proposed a multi-dimensional numerical model of the YBCO growth in the TFA-MOD process, which was established in consideration of the basic concept of the one-dimensional analytical growth model, multi-component diffusion and convective gas flow. It was confirmed that the calculated growth rate values were in good agreement with experimental ones. Furthermore, this numerical method revealed an effective tool to determine a suitable configuration of the gas flow in the reaction tube for a high production rate in long YBCO coated conductors.

As a method of the fabrication process of YBa 2 Cu 3 O 7ร€x (YBCO) coated conductors, the metalorganic deposition (MOD) process using metal trifluoroacetates (TFA) has been considered to be a strong candidate as a low cost fabrication process for coated conductors with high J c . In the case of the
