The NASA SBIR product catalog

The purpose of this catalog is to assist small business firms in making the community aware of products emerging from their efforts in the Small Business Innovation Research (SBIR) program. It contains descriptions of some products that have advanced into Phase 3 and others that are identified as prospective products. Both lists of products in this catalog are based on information supplied by NASA SBIR contractors in responding to an invitation to be represented in this document. Generally, all products suggested by the small firms were included in order to meet the goals of information exchange for SBIR results. Of the 444 SBIR contractors NASA queried, 137 provided information on 219 products. The catalog presents the product information in the technology areas listed in the table of contents. Within each area, the products are listed in alphabetical order by product name and are given identifying numbers. Also included is an alphabetical listing of the companies that have products described. This listing cross-references the product list and provides information on the business activity of each firm. In addition, there are three indexes: one a list of firms by states, one that lists the products according to NASA Centers that managed the SBIR projects, and one that lists the products by the relevant Technical Topics utilized in NASA's annual program solicitation under which each SBIR project was selected

Quantifying the Effects of HVAC Operation to Mitigate Aerosol Concentration in a Classroom using CFD

Heating, ventilation, and air conditioning (HVAC) is a complex mechanical system for the transition of air between outdoor and indoor areas. These systems are directly responsible for temperature, humidity, and air flow into any given space, thereby providing a level of comfort to those who live indoors. These systems account for 52 percent of U.S. energy consumption. When designing HVAC systems, indoor air quality (IAQ) is the main focus for achieving safe and clean air, such as in the case of airborne diseases. HVAC systems are responsible for the flow of air in indoor spaces and thereby expand the transmissible pathways of any given airborne virus. As a result, engineering and health organizations such as the World Health Organization (WHO), the Centers for Disease Control (CDC), and the American Society of Heating, Refrigeration, and Air conditioning Engineers (ASHRAE) have issued many guidelines. The focus of this study was to scientifically prove these guidelines and to determine whether the blanket statements provided by these organizations are supported by simulation results of various layouts in a university classroom setting. Computational fluid dynamics (CFD) is used as the foundation for software to determine the effects of mitigation strategies on the transmission of infectious aerosols. In this study, a university classroom located on South Dakota State University (SDSU) campus was modeled in computer-aided design (CAD) software and then imported into CFD software with a set of baseline physics conditions that would be used for various mitigation strategy. The mitigation strategies proposed in this study for the same university classroom are as follows: (1) airflow modification, (2) introduction of an acrylic barrier, (3) room layout adjustments, and (4) air redistribution techniques. Results show that the best and worst results are unique and there is no overlap between heating and cooling simulations sets. For instance, a bad result would be an overall increase in aerosols being distributed throughout the breathing zone of the room, whereas a good result would be a decrease in overall aerosols being distributed. Furthermore, there appears to be no one-size-fits-all solution throughout the calendar year, and each room under the influence of an HVAC system will have a unique strategy to mitigate the transmission of infectious aerosols

NASA SBIR abstracts of 1990 phase 1 projects

The research objectives of the 280 projects placed under contract in the National Aeronautics and Space Administration (NASA) 1990 Small Business Innovation Research (SBIR) Phase 1 program are described. The basic document consists of edited, non-proprietary abstracts of the winning proposals submitted by small businesses in response to NASA's 1990 SBIR Phase 1 Program Solicitation. The abstracts are presented under the 15 technical topics within which Phase 1 proposals were solicited. Each project was assigned a sequential identifying number from 001 to 280, in order of its appearance in the body of the report. The document also includes Appendixes to provide additional information about the SBIR program and permit cross-reference in the 1990 Phase 1 projects by company name, location by state, principal investigator, NASA field center responsible for management of each project, and NASA contract number
