In present work, comparison of three different tube bundles for particular heat exchanger is proposed. Three types are smooth, micro finned and corrugated tubes. Heat exchanger will be designed with smooth tube bundle and simulated. Micro fin and corrugation over tube is applied separately for same heat exchanger in feasible size and simulated for performance. Besides, comparison is done with h...
This paper discusses three instances of compositions, in which physical and cyber everyday objects interact. The physical objects such as plastic corrugated tubes, plastic superballs, glass marbles, cocktail shakers, electric blenders, and others provide unique musical data for the performance and input data for their physically modeled counterparts. Besides the compositional strategies, the ar...
The transient process accompanied by extreme acceleration in the conical sections of hydraulic systems (e.g., draft tube, diffuser) can induce large cavitation bubbles both at closed ends and bulk liquid. collapses cause severe damage to solid walls. We conduct experiments tubes with different conical-frustum shaped `tube-arrest' method observe generated these two locations. For close end we pr...
We present the application of a short rise ( 150 ns) 250 kA linear transformer driver (LTD) to wire array z-pinch loads for the first time. The generator is a modification of a previous driver in which a new conical power feed provides a low inductance coupling to wire loads. Performance of the new design using both short circuit and plasma loads is presented and discussed. The final design del...
This project utilizes integral calculus to find the exact volume of a non-uniform cylindrical-shaped silo used store wheat and calculate cost material utilized build such silo. Due its shape, is divided into two sections each calculated. The final for with measurements provided approximately 2330.02 meters cubic surface area 1074.96 squared, which considered be large capacity With there are cos...
We describe a fast figure metrology system designed for the several thousand mirror quadrants in the High Energy Focusing Telescope (HEFT) balloon experiment. HEFT's multilayer coated hard x-ray optics will have ~ 1 arcminute HEW and operate at 20-80 keV. The optics are a conical approximation to the Wolter-I configuration. Our automated system can measure the axial figure error, in-phase and o...
