Abstract: A system and method for computing thermal boundary conditions from an unstructured computational fluid dynamics (CFD) simulation for a thermal simulation of a structural component are disclosed. The thermal boundary conditions include convective heat transfer coefficient (HTC) and reference temperature (Tref). In one embodiment, prism cells are formed to capture boundary layer substantially next to a wall of the structural component. Further, tetrahedral cells are formed to capture a diffused temperature layer substantially next to the formed last prism cell and in a direction normal to the wall. Furthermore, temperature of each of the prism cells is computed in the direction normal to the wall until a substantially first tetrahedral cell. In addition, the computed temperature of the prism cell that is substantially adjacent to the first tetrahedral cell is declared as the Tref. Also, the HTC is computed using the obtained Tref.

Abstract: A novel optical sensor is used for monitoring the thickness of deposited thin film in real time. The sensor operates on the basic principle of a Fabry-Perot interferometer. A MEMS based design is used to fabricate the optical fiber sensor. Detail analytical results provide the theoretical model based on the Fabry-Perot interferometer, and show that the optical fiber sensor can successfully monitor and measure the thickness of deposited thin-film in real time. Since thin-film will be deposited simultaneously on both surfaces of sensor head and targeted silicon wafer, the sensor can be used in the fabrication of IC and MEMS devices j, as well as in proteomics, nano-sensors, and biosensors.
