In this paper, an attempt has been made to estimate the convective heat and mass transfer for pool boiling of sugarcane juice during preparation of jaggery. An indoor experiment was conducted to measure (i) the mass of evaporated water, (ii) the temperature of the sugarcane juice, (iii) the relative humidity above the sugarcane juice surface and (iv) the temperatures at the bottom and side of t...

Locations and response characteristics of nociceptive neurons in the dorsal horn of the spinal cord were studied in urethane-chloralose anesthetized Japanese macaques. There were two general categories of nociceptive neurons. Neurons of the first type, nociceptive specific (NS) neurons, responded only to intense mechanical stimuli. Neurons of the second type, wide dynamic range (WDR) neurons, w...

In order to study the heat transfer characteristics, a micro heat pipe (MHP) of circular geometry having inner diameter 1.8 mm and length 150 mm is designed and fabricated. An experimental investigation is carried out also to investigate the performance of the MHP with different experimental parameters. These experimental parameters include inclination angle, coolant flow rate, working fluid an...

This paper describes modeling and on-line optimization of a crude unit heat exchanger network at the Statoil Mongstad re nery. The objective is to minimize the energy input in the gas red heater by optimally distributing the cold crude oil in the heat exchanger network. The steady state mass and energy balance of the 20 heat exchangers in the network yields the process model. This model is tted...

This paper considers the maximisation of conversion by manipulating the input flowrate for an exothermic second-order esterification reaction (propionic anhydride + 2-butanol) performed in a semi-batch reactor. Safety considerations impose bounds on the heat release rate in normal operation and on the maximum attainable temperature in the case of cooling failure. The optimal input flowrate is c...
