Algorithms For The Solution Of Systems Of Coupled Second-Order Ordinary Differential Equations, Brendan O'Shea Jan 1978

Algorithms For The Solution Of Systems Of Coupled Second-Order Ordinary Differential Equations, Brendan O'Shea

Articles

Several step-by-step methods for the computer solution systems of coupled second-order ordinary differential equations, are examined from the point of view of efficiency “time-wise” and “storage-wise”. Particular reference is made to a system arising in the close-coupling approximation of the Schroedinger equation. The stability of the solution is also considered.


Heat Pump Evaluation And Design For The Irish Climate, Jim Mcgovern Jan 1977

Heat Pump Evaluation And Design For The Irish Climate, Jim Mcgovern

Other resources

The work of this thesis concerns the application of heat pumps to domestic space heating in Ireland. Only small air-source electric-powered vapour compression plants using fluorocarbon refrigerants are considered. Tests have been carried out on an air-to-air heat pump unit with a rated heat output of 3 kW. The performance characteristics of each of the system components have been determined from the test results. Computer programs have been written to calculate performance figures for theoretical heat pump cycles and refrigerants 12, 22 and 502 have been compared with one another on the basis of theoretical performance. A computer program has …


Heat Pump Research Programme At University College Dublin (1976), Seamus Timoney, Jim Mcgovern Jan 1976

Heat Pump Research Programme At University College Dublin (1976), Seamus Timoney, Jim Mcgovern

Conference Papers

This paper describes heat pump research at University College Dublin in 1976 relating to an air-to-air heat pump. The plant under test and its instrumentation are described and some measured performance data are presented. A heat pump simulation program is described. A theoretical comparison of refrigerants 12, 22 and 502 is presented with graphs of performance parameters as a function of operating conditions.
