Setup and results

Dataset 1

M. Schremb, C. Tropea; Solidification of Supercooled Water in the Vicinity of a Solid Wall; Physical Review E, Vol. 94, 052804 (2016).
https://doi.org/10.1103/PhysRevE.94.052804

The dendritic freezing of supercooled water drops entrapped in a Hele-Shaw cell has been captured with a high spatial and temporal resolution using high-speed video imaging. Information concerning the experimental setup and method is found in the aforementioned publication.

Information concerning the temporal and spatial resolution can be obtained from the time stamp and scale in the videos. The temperatures during the experiments are as follows:

video1_freezingSessileDrop.avi

T = -15.8 °C

Supercooled solidification of a sessile drop.

video2_freezingWithinHele-ShawCell.avi

T = -15.8 °C

Supercooled solidification of a drop in the Hele-Shaw cell.

video3_iceLayerPropagation.avi

T = -10.7 °C

Dendritic solidification of a drop in the Hele-Shaw cell.

 

Dataset 2

M. Schremb, J. M. Campbell, C. Tropea, H. K. Christenson; Ice Layer Spreading along a Solid Substrate during the Freezing of Supercooled Water: Experiments and Modeling; (2017). https://doi.org/10.1021/acs.langmuir.7b00930

The propagation of a thin ice layer prior to dendritic freezing of supercooled water drops entrapped in a Hele-Shaw cell has been captured with a high spatial and temporal resolution using high-speed video imaging. Information concerning the experimental setup and method is found in the aforementioned publication.

Information concerning the temporal and spatial resolution can be obtained from the time stamp and scale in the videos. The temperatures during the experiments as follows:

1_planar.avi

T = -2.44 °C

Small supercooling results in only planar growth of the initial ice layer.

2_lateDendrites.avi

T = -6.77 °C

Dendrites arise long after the spreading of the initial ice layer.

3_singleDendrites.avi

T = -8.53 °C

Single dendrites arise shortly after the spreading of the initial ice layer.

4_inhomogeneous.avi

T = -10.67 °C

Propagation of an inhomogeneous cloud of dendrites.

5_homogeneous.avi

T = -12.65 °C

Propagation of a homogeneous cloud of dendrites.
