Understanding the fluid flow and heat transfer characteristics within a vehicle compartment is very important for controlling the effect of major design parameters. Also, adequate visibility through the vehicle windshield over the entire driving period is of paramount practical significance. The numerical solution was done by an operation friendly, fast and accurate CFD code — SC/Tetra with a full scale model of a SM3 car and turbulence was modeled by the standard k-ε equation. Numerical analysis of the three-dimensional model predicts a detailed description of fluid flow and temperature distribution in the passenger compartment and on the inside windshield screen. During the cooling period, the lowest temperature is observed in the lower part of the windshield and in the vicinity of the defroster griller. It was found that the temperature dropped down to a comfortable range almost linearly at the initial stage. The initial period to achieve this comfortable range is dependent on the inlet velocity. Experimental investigations are performed to determine the localized thermal comfort and further validation of the numerical results.

The Relationship

In view of the practical significance in dynamical meteorology of the problem of evaporation from areas of finite lateral extent, it is a matter of fundamental importance to test as fully as possible the applicability of the hypothetical three-dimensional model of turbulence which was introduced by the author in 1947. The present paper describes in detail the manner in which the two-dimensional system developed by O. G. Sutton, K. L. Calder and E. L. Deacon for flow over aerodynamically smooth and rough surfaces may be extended to three-dimensional diffusion of vapour over an evaporating area. The agreement obtained between theory and experiment is good at points over the area. This agreement indicates that the assumed law, introduced by the author to give the variation of the coefficient of lateral diffusivity with height above the surface, may be used satisfactorily in evaporation problems as long as attention is confined to points not too far outside the boundaries of the area. The complicated mathematical relationship previously obtained for the vapour distribution vertically above the down-wind edge of a parabolic strip is reduced to a much simpler one. This serves to bring out explicitly the relationship between the effects of the two- and three-dimensional theoretical systems of turbulent transfer at points on the central axis of the area.

Presenting the results of a qualitative research on the practice of prayer in pastoral care, this article discusses the questions which most interest ministers in the Protestant Church in the Netherlands. Dialogue − between the pastor and the other, and between the conversation partners and God − is a key issue. The article presents a three-dimensional model of this dialogue and elaborates a theology of pastoral prayer as spiritual fellowship. It then argues that in pastoral care, ministers, with their conversation partners, should pay more attention to the theological quality and the practical significance of dialogue on praying together.

There are some problems in the design of three-dimensional visualization teaching resources, such as less involved in interactive design, no unified design standards, the lack of effective innovation guidance mechanism and no unified evaluation system. Based on the design principle, taking amino acids as an example, this paper proposes a design plan for 3D visualization resources in teaching scenarios. According to the design scheme, the three-dimensional visualization resources are made. The main processes include the selection of the tools, the preparation and production of the material, the writing of the script, the design of the learning interface, the design of the interactive logic relationship and the control and output of the program. Finally, the three-dimensional visualization resources are used in the future classrooms with starC electronic double board and group touch screen, and the results are analyzed and evaluated. It is found that the three-dimensional visualization resources can effectively improve the students' interest in learning and help students understand knowledge.

This article problematizes the relation between the cultural memory and the Gezi Park protests which took place in 2013 in İstanbul. With this aim, a sample of the literature as the source for the analysis were selected. The selection of the literary productions were made purposively in order to analyze the memory of the Gezi Park protests in connection with the general understanding of the cultural memory. The relevance of the literature to the role of memory in social protest was analyzed on the basis of the three dimensional model of the relation between memory and literature by considering the working of three aspects of mnemonic mimesis: prefiguration, configuration, and reconfiguration. Consequently, literature as the mimesis of memory was connected to the analysis of the cultural memory of social protest. It was argued that the cultural memory of the Gezi Park protests contributes to the repertoire of the memory of the social protests in novel ways.

AbstractReliable assessment of offshore sand and gravel resources permits efficient dredging, the maintenance of cargo quality control and the effective mitigation of environmental impacts. Site investigation should be based on the interpretation and correlation of high resolution seismic profiling and CPT/sampling data. A preliminary interpretation of the seismic data reveals the geological setting of the sand bodies and leads to the selection of appropriate sampling methods and the recognition of key sampling positions. Geologically complex sand bodies demand phased data acquisition to delineate geometry, physical properties and compositional variability. The alternative approach, of grid-based sampling using a predetermined sampling density, is costly at best and probably misleading. A three-dimensional model is created from the integration of acquired data and a resource volume calculated. Dredging constraints and overflow losses are applied to the model resulting in the determination of a reserve volume and critical dredging parameters. It is advisable to carry out a wide-ranging testing programme on the recovered samples to ensure compliance with relevant standards or requirements. The potential penalties for superficial site investigation include delay, unpredictable cargo quality and unforeseen environmental problems.
