CFD Cyber Education Service
• e-AIRS-CFD– Students can “learn by doing” whole processes of CFD– Traditional didactic lecture approach cannot attract students’ curiosity to
the real world problem– Cyber education system is present, lecture can expect the increase of
students’ understanding and curiosity
