Abstract
The experiment was conducted at the Palm Technology Company, Agricultural Research Corporation, Shambat-Khartoum North, Sudan. The objective of the study was to develop a mathematical model to simulate heat transfer in a greenhouse, and to validate the developed model by comparing measured temperatures data with the predicted ones. A one – dimensional conduction heat transfer model was developed to simulate heat transfer in a greenhouse. The model was written into a computer programme using Visual Basic 6 programming language. A greenhouse of quonset type with dimensions of 38m×8.5m×2.5m was used for carrying out the experimental work. Results showed that there is a close agreement between measured and predicted temperatures. Statistical analysis showed that the average model error, the average absolute difference and standard error of estimate for morning period are -0.1250, 0.6000 and 1.2196 respectively, while for the afternoon period they are -3.0000, 0.0750 and 0.4743 respectively. This indicates that the developed conductive heat transfer model predicted the temperatures in the greenhouse within the bounds of the experimental error.
