Ruin in the films of Jia Zhangke
No full textThis article explores the reflection, representation and psychogeographic affect of the ruins in the films by the Chinese filmmaker Jia Zhangke (b. 1970). During the Maoist period, ruins were signs of developmental progression; as Mao Zedong proclaimed, ‘there is no construction without destruction ... Put destruction first, and in the process you have construction.’ The author argues that the ruins are not just the effects of China’s fast-paced modernization, but are also symbols of the destruction of Maoist society. Furthermore, by recording the state and act of destruction, these films enhance the phenomenological and affective aspects of the ruin. Finally, when construction is realized in the films (the construction from destruction), it is either threatening or ‘futuristic’; thus, both the ruin and construction estrange the previous residents from their environment by rejecting them from the places that they once lived and chronologically estrange them from the projected utopian future
Entrainment studies in cloud-like flows using novel scanning tomography technique
No full textClouds are one of the major sources of uncertainty in climate prediction.The present work is to study the dynamics of orographic clouds. We considered a planar turbulent wall jet with off source volumetric heating as an appropriate low order fluid-dynamical model for studying the turbulence and entrainment in orographic-clouds. Entrainment was found to reduce drastically with the off-source volumetric heat addition. We found that the reduction of entrainment started at a bulk-Richardson number which was an order of magnitude smaller than that seen in earlier experiments [1] on free standing cumulus clouds. This is consistent with observations in real orographic clouds which develop as a thin sheet rising along the mountain slope. We have developed a novel scanning tomography technique for getting concentration field in turbulent shear flows. This technique is being applied on cloud-like flow to understand the entrainment characteristics. Detailed results will be presented at the conference
