Three-dimensional flow of a low-density polyethylene in a spiral die for blown-film extrusion is simulated. Effect of elongational viscosity on the flow in the spiral die is analyzed. Elongational viscosity is found to have significant effect on the velocity distribution at the die exit and on the pressure and temperature distributions in the die.

die vorliegende arbeit geht von dem versuch aus, die behandlung des dramas im sprachunterricht einzubeziehen. die grundgedanken sind: 1- abwechselung in den unterricht zu bringen; 2- die lernenden zur eigenen sprachtatigkeit anzuregen; 3- an der bildung der lernenden mitzuwirken. das drama "die physiker" ist in dieser arbeit als beispiel fur den deutschunterricht bearbeitet worden. die ziele hi...

a r t i c l e i n f o a b s t r a c t By demonstrating the importance of entrepreneurial exit to the entrepreneur, the firm, the industry, and the economy I contend that our understanding of the entrepreneurial process is incomplete without the inclusion of entrepreneurial exit. I define entrepreneurial exit and demonstrate how this conceptualization provides concepts that are unique from those...

die vorliegende untersuchung besteht aus drei theoretischen und praktischen teilen sowie zwei anlagen. in dem theroretischen teil wrird auf die lehrmethode hingewiesen. auberdem werden vierzehn unterschiedliche themen und die wichtigsten resultate der durchgefuhrten meinungesumfragen vorgelegt. fur den praktischen teil wurden als beispiel 14 zielgerichtete und zusammenhangende themen uber allta...

An axisymmetric jet issued from a sharp edged circular convergent nozzle has been studied experimentally in the near field at Reynolds number 5.3x104  to search the saddle shape behavior of mean velocity and the role of mean static pressure in the jet flow. Due to the vena contracta effect the centerline mean velocity of the jet increases about 4.2% of its exit value and corresponding decrease ...

One of reasons that researchers in recent years have tried to produce ultrafine grained materials is producing lightweight components with high strength and reliability. There are disparate methods for production of ultra-fine grain materials,one of which is severe plastic deformation method. Severe plastic deformation method comprises different processes, one of which is Parallel tubular chann...

An alternative to extrinsic information transfer (EXIT) charts called mean squared error (MSE) charts that use a measure related to the MSE instead of mutual information is proposed. Using the relationship between mutual information and minimum mean squared error (MMSE), a relationship between the rate of any code and the area under a plot of MSE versus signal to noise ratio (SNR) is obtained, ...

In this paper the influence of different parameters on equal channel angular pressing (EADAP) of titanium alloy is investigated. In the first step the most important parameters are selected, and then a table of experiments is designed using Taguchi method. After designing the table of experiments, all of the experiments are simulated using Abacus software and the results are optimized using Tag...
