Modelling and Structural Analysis of Ice Strengthened Vessel
Abstract: Abstract In this paper, one global and one local FE-model are developed in order to calculate the response of ice loading on an ice strengthened 100.000 DWT oil carrier. A global analysis is performed by applying loads in two different areas in the bow region. The deformations of the global model are used as boundary conditions in the analysis of the local model. In each of the two areas, the …

Experimental Set Up of Optical Tomography Probe and Visualization of Characteristics of a Taylor Bubble
Abstract: Abstract Conventional methods for the detection of bubbles uses probes which physically protrude into the flow field and thus may affect the flow dynamics, thereby tethering the formation, development and flow of bubbles. In thermal power plant, it is rather difficult to physically see which type of two phase flow is happening in the pipe. In such a case, an optical tomography sees its application. Depending upon the type of …
