The forward challenges in translating the holy Quran are the large differences caused by the differences in the interpretations of the verses. As, a translator is obliged to be faithful to the interpreters’ views, for solving this challenge, there is a need for having an exact criterion and in accordance with linguistic logic of the holy Quran, in order to judge the diverse interpretative views.  The criterion, accordingly, is the product of having the structural approach to the holy Quran. Because having such an approach, is a knowledgeable attempt in finding the wisely geometry of surahs, and takes us to what The All-Wise Allah, aimed at the sending the text of the Quran. This article by using a descriptive-analytical method and by elicitation of the geometrical structure of Surah Al-Imran and analyzing the differences in translating some verses of this surah, and investigating the extent of adaption of each of these interpretative views with compatibility index of the general purpose, resulted from the geometrical structure of the surah, aims at answering the question that how we can use the systematic or structure-based views for criticizing a translation. Some of the results are as follows: First of all, considering the fact that Quran, itself, is a criterion for analyzing everything, included the speech of Ahl-Albayts (SAW), then the criterion of analyzing the interpretive ideas must be intra-textual; and this is the same purpose derived form the geometrical structure of the surah. In this view, the words and verses of each surah are the building blocks that are organized around one single center. Therefore, each interpretive idea or translation is not acceptable if it is not compatible with the purpose of the surah and place of the verse in the structure. Secondly, the translation of the selected verses of Sural Al-Imran have been determined as objective instances to this analytical criterion and interpretive views adapted to the structure of surah and exact translation based on them.

Abstract- Possibilities and limitations of 1D and 3D flow simulations in the vaneless turbocharger turbine of a 1.7 liter SI engine are presented experimentally and numerically. A test setup of the turbocharged engine on dynamometer is prepared to validate the results of numerical modeling. Various performance parameters are measured at 12 different engine speeds and the results of measurement in 3 different engine speeds are presented in this report. The complete form of the volute and rotor vanes is modeled. An extensive study on the number of meshes has been undertaken to ensure the independency to meshes. The modeling of rotating wheel is considered by Multiple Rotating Frames (MRF) technique. Finally, the variations of turbine performance parameters are studied under different pulse frequencies of the engine. The results show that at high engine speeds a 3D unsteady flow simulation is required to get reasonably accurate results. The results presented in current report will be used in simulating three dimensional steady and unsteady compressible flow within the turbine of the turbocharger.
