Report of the Treasurer: 1977. Revenues, expenses, and all that jazz.

Presents a report from the American Psychological Association's treasurer for the year 1977. Because APA's activities and materials are largely in publications, and since these constitute over half of our annual revenues, the first part of this year's Treasurer's Report is devoted to a selective overview of our publication programs and operations. The financial portion of the report includes (a) a report of the 1976 audited results from operations; (b) a look at APA's financial condition as of December 31, 1976; (c) a prediction for 1977; (d) a review of the 1978 approved budget; and (e) a projection for 1979.

Predicting the Mean Annual Flood for Small Catchments: Experience in Northern Ireland

The paper describes six alternative equations for predicting mean annual flood from catchment characteristics, developed in and subsequent to the UK Flood Studies Report and tested for ten small catchments in Northern Ireland. The most satisfactory equation was found to be one developed in the mid-1980s for large catchments in the Province. Equations which were developed using small-catchment data from elsewhere in the UK performed less well. The paper considers whether there is a real difference in the behaviour of small and large catchments in Northern Ireland, and examines alternative methods of estimating the mean annual flood in partly-urbanised areas.

Flow boiling of ammonia in a plain and a low finned horizontal tubeEbullition en éncoulement d'ammoniac dans un tube lisse ou un tube ailetté

Experimental data of the local heat transfer coeffcient of flow boiling ammonia in dependence of vapor fraction, mass flux and local heat flux is presented. Two horizontal test sections of 450 mm length and an inner diameter of 10 mm have been used, one being a plain tube, one being a spirally low finned tube. A constant wall temperature boundary has been aimed for the test section by heating with a fluid condensing on the tube outside. Local heat transfer coeffcients and pressure drops have been measured in the range −40 < T_sat < 4°C, 0 < x< 0.9, 50 < < 150 kg/m² s and 2 < ΔT_w < 15 K with resulting heat fluxes of 17 < < 75 kW/m². The vapor quality is denoted as x, is the mass flux and ΔT_w the wall superheat. The measured data is carefully evaluated using a finite element model of the tube with regard to the circumferential heat flow distribution. The smooth tube results are compared with recently published data and the correlation from Zürcher (Zürcher, O., Thome, J.R., Favrat, D. Evaporation of ammonia in a smooth horizontal tube: heat transfer measurements and predictions. Journal of Heat Transfer, 1999;121:89–101), and with the correlations of Steiner (Steiner D. Strömungssieden gesättigter Flüssigkeiten. VDI-Wärmeatlas, vol. 8. VDI-Verlag, 1997) and Kattan (Kattan N, Thome JR, Favrat D. Flow boiling in horizontal tubes: part 3 — development of a new heat transfer model based on flow pattern. Transactions of the ASME, 1998;120). The results of the low finned tube are not matched by any known correlation.     

Two-phase heat transfer to a refrigerant in a 1 mm diameter tubeTransfert de chaleur vers un frigorigène circulant dans un tube d'un diamètre d'un mm

A study of two-phase flow and heat transfer in a small tube of 1 mm internal diameter has been conducted experimentally as part of a wider study of boiling in small channels. R141b has been used as the working fluid. The boiling heat transfer in the small tube has been measured over a mass flux range of 300–2000 kg/m² s and heat flux range of 10–1150 kW/m². In this paper the boiling map for a mass velocity of 510 kg/m² s and heat flux of 18–72 kW/m² is discussed and the problems of determining heat transfer coefficients in small channels are highlighted.
