Mechanism of Heat Transfer in Solid and Fluids

Aim  “To understand the mechanism of heat transfer in solid and fluids” Aim of this task is to understand the mechanism behind the heat transfer in solid and fluid under control environment. Mechanism of heat transfer inside solid material, between two different solid materials and between solid and fluid will be discussed in this lab work. Objectives In order to understand the mechanism of heat transfer in solid and fluids the below mention objectives should be completed fully in said sequence. Understand the basic of heat transfer in solid and fluid using the mechanism of conduction and convection Understand the mechanism of forced convection at the interface of the fluid and solid Understand the basic of energy balance in the system of heat transfer Perform experiment to analyze the force heat transfer and energy balance when air flow inside heated tube Theory  Conduction The process of heat transfer in solid material happen due to the mechanism of heat transfer called conduction.

Organic Fluids and Rankine Cycle (selection process for organic fluid)

In organic Rankine cycle, an organic fluid is used in the place of water to reduce the cost of heating done in the boiler. The organic fluid used has a lower boiling point as compared to water due to which it requires less heat in the boiler to produce the organic fluid steam and it also requires less energy at condenser for cooling (S. Quoilin 2011). Less heat requirement means low fuel-burning which reduces the cost of operating the Rankine cycle. The organic fluid selected for the organic Rankine cycle is evaluated on strict selection criteria and the fluid performing the best is select as working fluid. The selection criteria of the organic fluid consist of thermal properties that influence the performance of organic fluid or are very critical for the basic working of the organic Rankine cycle.  Following is the list of thermal properties and why they are important for the evaluation of the organic fluid of organic Rankine cycle 1. Heat Capacity The heat capacity of the fluid is de

5 Eco Friendly Heat Energy Resources for Organic Rankine Cycle

Organic Rankine cycle ORC is one of the best options available for small scale efficient energy production systems. In Organic Rankine Cycle an organic fluid is used in the Rankine cycle instead of water as the organic fluid has a lower boiling point as compared to water so required less heat input. Waste heat from any source, when combined with organic Rankine cycle ORC using a heat exchanger like shell and tube heat exchanger, make it the best and most environmentally friendly energy solution. Optimize parameters allows the minimum mass flow rate and less area required for the heat exchanger saving power and cost required at the heat exchanger system without compromising the efficiency of the system.  With a continuous increase in the world population, the problems associated with human needs are also increasing. One such problem is the need for energy to meet certain needs like electricity. In today’s industrial world where there is a complete working industry for every human need,
