In this paper, numerical simulation has been carried out to study effect of heater power allocation on the thermal stress evolution during Kyropoulos sapphire cooling process.
The thermal design of blackbody proposed in this study consists of heaters to heat-up the blackbody during the calibration, heat pipe to transfer residual heat on the blackbody just after calibration to radiator on the spacecraft and heaters on the radiator to keep the certain temperature range of the blackbody during non-calibration.
Study of the developed heater is conducted; using different porous disc thicknesses of (20, 40, 60 mm), heater wall temperatures (106 °C and 119 °C), and flow rates rare varied from (100 300 L/min).
The results of a detailed thermo-hydraulic performance study of solar air heater with v-down discrete rib roughness using the mathematical model are also presented along with the effect of variation of various parameters on the performance.
This paper reports on a modelling study of new solar air heater (SAH) system by using artificial neural network (ANN) and wavelet neural network (WNN) models.
In the first part of the study the heater was a vertical spiral tube positioned coaxially with the tank.
The nature of oscillations in terms of their amplitude and frequency and their evolution for Type-I and Type-II instabilities are studied with respect to the effect of heater power and pressure.
A randomised prospective study of endoscopic bipolar electrocoagulation and heater probe treatment of chronic rectal bleeding from rectal telangiectasia (n =21) Selection criteria included pelvic RT at least 2 years earlier, rectal bleeds at least three times per week, anaemia, having failed 1 year of medical therapy and consideration for surgery, and a life expectancy of 2 years.
Thus, to infer the general effect of heater size from previous studies, the maximum CHF enhancements of alumina-water nanofluids on flat-plate heaters exclusively are plotted against the dimensionless heater size L', (1).
The design and fabrication for a thermal chip with an array of temperature sensors and heaters for study of micro-jet impingement cooling heat transfer process are presented.
The design and fabrication for the thermal chip of a heat exchanger with arrays of temperature sensors and heaters for study of micro-jet impingement cooling heat transfer process is presented.
