Numerical Study on Heat Transfer Enhancement of Laminar Flow through a Circular Tube with Artificial Rib Roughness
Abstract: This work presents the configuration optimization of a typical square roughness in a circular tube for laminar heat transfer in air using computational fluid dynamics (CFD) modelling. Conjugate heat transfer 2D numerical model has been developed and successfully carried out. CFD numerical simulations were carried out to analyze the flow and heat transfer in the air duct of a solar air heater provided with rectangular ribs. The laminar flow model …

Fabrication and Design of AC Water Heater
Abstract: As we know the construction of split air conditioner where we put evaporator unit indoors which gives cool conditioned air meanwhile the condenser is kept outside or outdoors which continuously give heat to the environment from refrigerant during the time of air conditioner is working. The heat which is getting discharge from the condenser is very large enough that it ranges between 4 and 6 times greater than power of …

Numerical Study on Thermal Performance Assessment of a Compact Heat Exchanger Equipped with Two Broken Twisted Strips
Abstract: Twisted strips are a widely used technique for heat transfer enhancement. In the present study, it proposed that two broken twisted strips aiming at achieving good thermohydraulic performance. Effects of the two broken twisted strips (BTS) on the heat transfer, friction factor and thermal performance factor behaviours in a heat exchanger are reported along with smooth duct. The computations are based on the finite volume method with the SIMPLE algorithm …

HYBRID TEG SYSTEM FOR INDUSTRIAL AND AIR CONDITIONING APPLICATIONS
Abstract: A new system to generate electric energy using thermoelectric generators (TEG’s) based on Peltier cells has been conceived, designed and built. The system consists of a Peltier cell assembly installed in a replica of an air conditioning circuit to benefit from hot and cold air flow to generate the appropriate temperature gradient. The new system has been characterized using a group of Peltier cells mounted on a dual thermostatic chamber …

Investigation of free convection heat transfers in an attic shaped eclosure
Abstract: Absrtact Numerical investigation of free convection heat transfers in an attic shaped enclosure with differentially heated two inclined walls and filled with air is performed in this study. The left inclined surface is uniformly heated whereas the right inclined surface is uniformly cooled. There is a heat source placed on the right side of the bottom surface. Rest of the bottom surface is kept as adiabatic. Finite volume based commercial …

Self-Starting Diesel Generator
Abstract: Power outages can happen to anyone, and they are a lot more frequent than the major outages that make the evening news on TV. Being prepared for a blackout goes beyond beans, batteries and bullets. Having a source of alternative energy to power your devices, both small and medium, can make all the difference. Larger devices can be powered, but you would need some serious generators to make sure you …
