NASA contributions to fluidic systems: A survey

A state-of-the art review of fluidic technology is presented. It is oriented towards systems applications rather than theory or design. It draws heavily upon work performed or sponsored by NASA in support of the space program and aeronautical research and development (R&D). Applications are emphasized in this survey because it is hoped that the examples described and the criteria presented for evaluating the suitability of fluidics to new applications will be of value to potential users of fluidic systems. This survey of the fluidics industry suggests some of the means whereby a company may use a fluidic system effectively either to manufacture a product or as part of the end product

Electronics Thermal Management in Information and Communications Technologies: Challenges and Future Directions

This paper reviews thermal management challenges encountered in a wide range of electronics cooling applications from large-scale (data center and telecommunication) to smallscale systems (personal, portable/wearable, and automotive). This paper identifies drivers for progress and immediate and future challenges based on discussions at the 3rd Workshop on Thermal Management in Telecommunication Systems and Data Centers held in Redwood City, CA, USA, on November 4–5, 2015. Participants in this workshop represented industry and academia, with backgrounds ranging from data center thermal management and energy efficiency to high-performance computing and liquid cooling, thermal management in wearable and mobile devices, and acoustic noise management. By considering a wide range of electronics cooling applications with different lengths and time scales, this paper identifies both common themes and diverging views in the thermal management community

Simulation verification techniques study. Subsystem simulation validation techniques

Techniques for validation of software modules which simulate spacecraft onboard systems are discussed. An overview of the simulation software hierarchy for a shuttle mission simulator is provided. A set of guidelines for the identification of subsystem/module performance parameters and critical performance parameters are presented. Various sources of reference data to serve as standards of performance for simulation validation are identified. Environment, crew station, vehicle configuration, and vehicle dynamics simulation software are briefly discussed from the point of view of their interfaces with subsystem simulation modules. A detailed presentation of results in the area of vehicle subsystems simulation modules is included. A list of references, conclusions and recommendations are also given

DEVELOPMENT OF A GAS-BASED APPLICATION FOR FIRE MODELING IN THE PROCESS INDUSTRIES

The major hazards with which the chemical industry is concerned are fire, explosion and toxic release. Of these three, fire is the most common. In assessing the damage potential and causes or errors which have led to these disasters, an analysis has to be done. The impacts of fires in the process industries may be predicted by the application of mathematical models. However, the applications of these models require competency in mathematics and computer programming. Therefore, the objective of this project is to develop an application called the Fire Simulation Tool (FiST), which is able to study the impact of fire in the process industry. The scope of work for this project is confmed to fire cases only, which are: flash fire, jet fire, pool fire and fireball. The FiST application is developed using Visual Basic (VB) programming language with integration of GIS tools. The mathematical models of the four types of fire are simulated and the results are integrated to GIS for better visualization. The development is done by customizing MapObjects using VB. With MapObjects user can incorporate mapping capabilities in their application. The methodology of the project includes utilizing established models in order to calculate the impact of fire. The development of this software has been divided into five different stages, which are planning the application, building the graphical user interface (GUI), writing the computer programme, software validation and verification and lastly, integrating the results from the tool with GIS application to present the simulation outcome as buffer zones around the centre of the accident. The results from FiST software is verified and validated with other risk assessment softwares such as: FRED (developed by Shell Global company, 2004), BIS (developed by ThermDyne Technologies Ltd, 2003) and SCIA (developed by EI-Harbawi, 2006) and with established data. The software is capable to estimate the thermal radiation and the impacts from the fire scenarios which include the probability of frrst, second and third degree of bums for the hmnan skin. The FiST application is useful and feasible because it is user-friendly, able to function as a stand-alone application and it is compatible with all windows operating system. Furthermore, the cost of developing the software is cheap and the application incorporates the risk tolerability limit for Malaysia
