Introduction Heat transfer is an essential process involved in chemical engineering. This transfer mainly considers the change in temperature as its focus. Most of the processes involved in the industry tackle this type of transfer. To aid engineers and even students in understanding this, heat exchangers were created. Heat exchangers are devices designed to prevent other machines from overheating. And there are several types existing. One characteristic common to most heat exchangers is the transfer of heat
effect on heat transfer enhancement in rectangular channels with triangular baffles Yogesh Sharma UIET Kurukshetra +91-8930381152 Yogesh5853@ymail.com Dr. ParinamAnuradha Asst Professor, UIET, Kurukshetra Abstract The thermal performance of a heat exchanger depends upon various parameters like inlet temperature of a hot fluid, type of hot fluid, type of cold fluid, shape of baffles, material of baffles, baffles angle and property of ribs. Basically fluid flow and heat transfer characteristics
HEAT EXCHANGERS AND HEAT INTERCHANGERS A wide variety of heat transfer equipments are used in pharmaceutical industries. They may be used to heat fluids i.e., liquids and gases and some time even solids. Heating media used is generally the hot fluid or steam or direct heating using electric heated coils. Some of the processes which involve heat transfer in pharmaceutical industry are: • Evaporators • Distillation • Drying • Crystallization • Preparation of semisolid dosage forms- creams, ointments

technique where heat transfer media conveys the thermal energy to the cooking pot. This technique is suitable for cooking both indoors and outdoors. Generally, there are three available types of indirect solar cooker as shown in Figure 4: flat-plate collector, evacuated tube collector and concentrating type solar cooker [21]. The collectors are separately located from the cooking unit and the two parts are connected together by heat exchanger pipes. In all these types, an effective heat transfer medium is
thermal management Heat transfer in microchannels plays an important role in microreactor systems in terms of heating the reacting fluids or the removal of the heat of exothermic reaction. Easy conduction of heat avoids sintering, thermal run-away and unwanted side reactions. For catalytic reaction, the ability to control the catalyst temperature, and therefore the selectivity, of partial reactions is the key factor determining reactor performance. In laminar flow, the heat transfer coefficient is inversely
The jet system theory The jet system is formed due to the interaction of free turbulent jets, issuing from nozzles (openings) that are arranged in a different geometrical way in the outlet plane. Stankov (1998) has investigated experimentally wide range of jet systems, issued from nozzles with square, circle and rectangular shape. He has found that the nozzles can be arranged, following schemes, which makes easier the prediction of the flow, issuing from a jet system with endless number of openings
alternating magnetic field through an induction coil. Therefore, placing a cooking pan below the induction coil will induce eddy current in the pan. As a result of which, heat energy will be produced on the surface of the pan. The internal resistance of the pan causes heat to be dissipated. Thus, it is the pan itself and not the heater that heats up and cooks the food
microscope: a smear or a wet mount. A smear involves the placing the live microorganism on a slide and letting it air dry. Once the slide is dry, wave the back of the slide in front of the incinerator. The heat from the incinerator will cause the microorganism to stick to the slide, which is know as heat fixation. If the microorganism needs to be viewed under the 1000x magnification, oil immersion is used. A wet mount is when the microorganism is suspended into a drop of water on a slide. The microorganism
humidity. The metabolic rate is decided by the human activitylevel.The heat loss from the body is decided by the clothing insulation value, the speed of body movement, openings in clothing and climatic conditions. The amount of thermal insulation of clothing worn by a person has a substantial impact on thermal comfort, because it influences the heat loss and consequently the thermal balance. Layers of insulating clothing prevent heat loss and can either help keep a person warm or lead to
