Solid-liquid interface evolution of d = 260 mm TC4 round ingot (a) with varying inlet velocity, (b) presents with 3D morphology at steady state for picked case of inlet velocity variation, (c) with varying inlet temperature, (d) presents with 3D morphology at steady state for picked case of inlet temperature variation, (e) with synchronously variated inlet and surface temperature, and (f) presents with 3D morphology at steady state for picked case of synchronously variated inlet and surface temperature.
