Bananas are to be cooled from 24 to 138C at a rate of 215 kg/h by a refrigeration system. The power input to the refrigerator is 1.4 kW. Determine the rate of cooling, in kJ/ min, and the COP of the refrigerator. The specific heat of banana above freezing is 3.35 kJ/kg8C.
CFD Lab: Office Hours 10-12pm Room 160A Grades: 3 or 4 quizzes, 4 reports, attendance. We will first be going through the basic to understand what we are going to be using the finite element analysis for. Applications CFD: 1. Meteorology 2. Aerospace 3. Roto-Dynamic Machines 4. Hydrodynamics (Ships) 5. Bio fluidics (Blood flow through arteries, veins, & heart) Intro to CFD: Purpose - To predict fluid flow, heat & mass transfer, chemical reactions, and related phenomena by solving numerically the set of governing mathematical equations. We use a simplification of the Stokes Equation in CFD. Steps: • Problem Identification ◦ Define Goals ◦ Identify Domain • Pre-Processing ◦ Geometry ◦ Mech ◦ Physics ◦ Solver Settings • Solve ◦ Compute Solu
