Finite Elements for Heat Transfer Problems

Finite element analysis (FEA) is a simulating process of the manner and assembly of an object under obtained conditions. It is used for assessing the finite element method (FEM) which includes one or more solution algorithms. General problem areas of interest are structures, heat transfer, the flow of fluid, transport, and some boundary value problems.

A well-insulated turbine operating at steady state is shown on the right. Steam enters at 3 MPa, 400°C, with a volumetric flow rate of 85 m³/min. Some steam is extracted from the turbine at a pressure of 0.5 MPa and a temperature of 180°C. The rest expands to a pressure of 6 kPa and a quality of 90%. The total power developed by the turbine is 11,400 kW. Kinetic and potential energy effects can be neglected. Determine (a) the mass flow rate (in kg/s) at each exit, and (b) the diameter of the duct, d₂ (in cm) where steam is extracted P₁ = 3MPa T₁=400°C (AV)₁ = 85 m³/min Turbine P2 = 0.5 MPa T₂ = 180°C V₂= 20 m/s Power out ¹3 P3= 6 kPa x3 = 90%

Question 3.3 When the air with a pressure of 0.1 MPa and a specific volume of 0.8 m³/kg was provided into a compressor at a flow rate of 0.25 kg/s, its pressure became 0.7 MPa and its specific volume became 0.2 m³/kg. Through the compression, the specific internal energy was increased by 80 kJ/kg, and there was heat loss of 50 kJ/s to the environment. In this case, calculate the work [k]/s = kW] that the compressor did in unit time. Potential energy and kinetic energy can be negligible.
1. A Rankine cycle with reheating has a throttle pressure of 135 bars at the turbine inlet and 28 bars reheat pressure, the throttle and reheat temperature of the steam is 550C, condenser pressure is 0.035 bar, mass flow rate of steam is 10 kg/sec. Draw the T-s and schematic diagram of the cycle and determine the following: (c) theoretical thermal efficiency (d) the steam rate (e) heat rate of the cycle
Steam at a pressure of 0.08 bar and a quality of 99.0% enters a shell-and-tube heat exchanger where it condenses on the outside of tubes through which cooling water flows, exiting as saturated liquid at 0.08 bar. The mass flow rate of the condensing steam is 5.8 x 105 kg/h. Cooling water enters the tubes at 15°C and exits at 35°C with negligible change in pressure. Neglecting stray heat transfer and ignoring kinetic and potential energy effects, determine the mass flow rate of the cooling water, in kg/h, for steady-state operation. mwater = i 568765.92 kg/h
