Chakole M.M. Heat Transfer Enhancement Techniques. With Special Attention to Passive Methods of Heat Transfer Enhancement

Heat exchangers are widely used in the industrial sector, e.g. in the refrigeration, air conditioning, petrochemical, and agricultural food industry. The high cost of energy and material has resulted in an increased effort aimed at producing high performance heat exchanger equipment. Passive methods of heat transfer enhancement do not need external power for enhancement. One of these kinds of passive technique is twisted tape inserts that enhance the performance of heat exchangers. Using multiple twisted tape inserts gives better enhancement than a single twisted tape insert. Using nanofluid gives also better thermal performance than water. Therefore, nanofluid along with twisted tape inserts was used in this study.For this study, different combinations of multiple twisted tape inserts were designed and fabricated. These different combinations contain dual, triple, and quadruple twisted tapes. Directions of twists are also varied which enables to study the effect of different swirl flow generators. Nanofluid is used with various volume concentrations of 0.07%, 0.14% and 0.21% in order to investigate the effect of nanoparticle concentration on heat transfer enhancement. Experimental investigation was carried out by having a constant heat flux condition and by varying the volume flow rate of flow from 2 to 10 lpm.

Osama Mohammed Elmardi Solutions to Problems in Heat Transfer. Transient Conduction or Unsteady Conduction

Many heat transfer problems are time dependent. Such unsteady or transient problems typically arise when the boundary conditions of a system are changed. For example, if the surface temperature of a system is altered, the temperature at each point in the system will also begin to change. The changes will continue to occur until a steady state temperature distribution is reached. Consider a hot metal billet that is removed from a furnace and exposed to a cool air stream. Energy is transferred by convection and radiation from its surface to the surroundings. Energy transfer by conduction also occurs from the interior of the metal to the surface, and the temperature at each point in the billet decreases until a steady state condition is reached. The final properties of the metal will depend significantly on the time - temperature history that results from heat transfer. Controlling the heat transfer is one key to fabricating new materials with enhanced properties.The author's objective in this textbook is to develop procedures for determining the time dependence of the temperature distribution within a solid during a transient process, as well as for determining heat transfer between the solid and its surroundings. The nature of the procedure depends on assumptions that may be made for the process. If, for example, temperature gradients within the solid may be neglected, a comparatively simple approach, termed the lumped capacitance method or negligible internal resistance t...

Milan Kvakovský The Heat Pumps

The heat pump is a machine that draws heat from one place to another investment of external work. Usually it is from the colder to warmer place. Heating heat pump is a device that uses non-traditional sources of energy for central heating and hot water. The basic view of heat pumps is that the planet's global temperature regime is directly added heat from the combustion of any fuel. Indirectly, there is a certain amount of heat in power plants - the production of electricity consumed for heat pump operation. In the first part of my project I explain the heat pump principles. Then are described the heat sources for heat pumps, divide the heat pumps depending on driving mechanisms, heat sources and using energy. This part also described the heat pumps like water to water type, earth to water type, air to water type, the basic parts of the heat pump like compressor and convertible of heat. Second part describes using the heat pumps like onditioning, heat pump like alternative source in household and different systems. The third part contains calculations of heat decreases and heat pump design. Finally are compared different types of heating with heat pump.

Soliman Wagdi Saber, Sugiyama Shu-Ichi Physiological Mechanisms of Heat Stress Tolerance in Turfgrass

Improving tolerance to heat stress is a major challenge in many crops, especially C3 crops, given the threat of recent global warming. While significant achievements have been made on understanding the molecular and physiological mechanisms to short-term exposure to high temperature, the physiological mechanisms of summer tolerance in fields, which are characterized by prolonged exposure to high temperature stress, are not still well understood. In this study, six experiments were conducted to clarify the physiological mechanisms of tolerance to high temperature stress by comparing between genotypes, populations and different species including C3 and C4 photosynthetic types. Overall, although the complexity of heat tolerance was revealed by the involvement of various mechanisms such as suppression of ROS, scavenging of toxic ROS, and leaf functions, this study definitively showed that the oxidative stress resulting from the excessive production of ROS is the main cause of damages under heat stress.
