RIT ME Department’s Mission Statement

The ME faculty have adopted the goal of establishing our department as one of the

top 25 ME programs first in the nation, and then in the world. Based on a strategic

planning retreat in May 2008, the faculty agreed that we, collectively as a

department and in collaboration with others, should accomplish three tasks, in

pursuit of our goal:



Demonstrate a revolutionary advance in engineering education whereby we
turn every entering student into graduates who achieve outstanding success.


Provide solutions to three compelling problems of national and global
significance.


Other ME departments must emulate us. We must disseminate our model of
education and research, and become the role model to which other institutions
aspire



ME and
ChemE

departments want new hardware for
demonstrations and laboratory experiments.


Hardware is to target areas related to the principles
of thermodynamics and heat transfer.


Students will be able to apply theoretical knowledge
to real life.


Project will greatly impact future generations of RIT
mechanical and chemical engineering students.

Fluids Lab 1 Description


Procedures reinforce topics
covered in
Thermodynamics
and
Fluid
Mechanics


Experiments quantify
the differences between real and
ideal systems through rigorous system
analysis


Extensive
analysis is used to calculate system
characteristics and to graph and predict system
behavior


Strong emphasis is placed on data collection methods, data
interpretation methods, error propagation, discussion of
error reduction and experiment documentation

Thermal
-
Fluids Lab 1 Layout

Weeks 1
-
2:

Vortex Tube Characterization


Learn about the concept of a vortex tube and the different types
manufactured


Record input and output parameters for two types of vortex tubes and
plot the data in order to characterize them accordingly


Thermal
-
Fluids Lab 1 Layout

Weeks 3
-
4:

Vapor
-
Compression
Refrigeration


Review basic refrigeration
concepts studied in
thermodynamics


Observe and record the state of
the working fluid throughout
the refrigeration cycle


Use the recorded data to
calculate thermodynamic
properties at each state point
through out the cycle


Use the recorded data to create
a p
-
h diagram for an ideal case,
and to calculate cycle
performances

Weeks 5
-
6:

Operation and Performance of Centrifugal Pumps


Learn about the function and performance characteristics of centrifugal
pumps


Record and plot the performance for pumps run alone, in parallel and
in series, compare the performance of “similar” pumps


Write a clear lab procedure for recording the pump data

Weeks 7
-
9:

Reynolds Pipe Flow


Review basic flow concepts studied in fluid mechanics


Calculate flow properties (mass flow, viscosity, theoretical entrance
length, etc.) for laminar and turbulent flow conditions


Record the pressure distribution along a pipe for both cases, and
compare it to the minimum and maximum theoretical distributions
resulting from the error in the properties mentioned above


Thermal
-
Fluids Lab 2 Description


Students design and conduct their own experiment on a
topic of interest relating to Heat
Transfer
and Transport
Phenomena


Students
are required
to work on the experiment and
analyses through out the quarter


Students
submit a detailed lab report that is graded on the
technical content as well as writing skills
.


Strong emphasis is placed on error propagation and
discussion of error reduction

Chemical Principles Lab Description


Reinforce topics covered in Thermodynamics and Fluid
Mechanics.


Students are introduced to basic equipment and methodologies
for designing laboratory experiments, measuring results,
interpreting data, and drawing objective conclusions


Students work in teams of 3
-
4 to design experimental
procedures, identify lab equipment, and assemble simple
apparatus to achieve specific experimental goals


Strong emphasis is placed on student independence and ability
to design and adapt lab procedures for specific applications


Assignments and lab write ups are relatively short

Chemical Principles Lab Layout

Week 1:

Introduction to equipment and pump function


become familiar with the lab equipment


learn how various pump types function

Week 2:

Pump analysis and valve studies


Study/develop pump performance curves and pump efficiency


Study the valve’s operating principles and plot valve coefficient vs. %
lift

Week 3:

Pressure drop
studies


Study the relationship between pressure drop and pipe/flow
parameters (laminar)



Mass Flow Apparatus

Chemical Principles Lab Layout

Week 4:

Heat Transfer lecture/review


Review basic conduction and convection principles and pose the
question: How can we measure the thermal conductivity of a specimen
?

Week 5:

Fluid concentration


Use spectroscopy to measure the concentration of different fluids

Week 6:

Kinetics


Compare experimental reaction rates to analytical reaction rates

Week
7:

Fluid Viscosity


Study Newtonian and non
-
Newtonian fluids


Determine fluid viscosities using the “Brookfield Viscometer”




Chemical Principles Lab Layout

Week 8:

Convection/Heat Exchangers


Calculate experimental total heat transfer coefficients for parallel flow
and counter flow heat exchangers, compare values to analytical
predictions

Week 9:

Perform student designed conduction lab


Calculate the thermal conductivity of different materials using the
designed lab, compare the experimental values with textbook
values

Week 10:

Cross flow filtration


Learn to filter particles out of a fluid using a membrane in tangential
flow filtration



Unit Operations Lab Description


Note that this lab currently does not exist


The chemical engineering department has
approximately $300,000 to design this lab that
will begin Fall 2012


The lab will teach students how to utilize large
pieces of equipment used by chemical engineers
(chemical reactors, distillation columns, etc.)


The lab will bring together all of the concepts
studied in the chemical principles lab

Background Research

Existing interactive
website that covers
a variety of
engineering topics
designed by the
makers of Wolfram
Alpha

Background Research Cont.

Existing demo from Boston University showing
Entropy

Background Research Cont.

Radiation demo from Northeaster Illinois University


Background Research: Thermodynamics


Most difficult topic for students to
grasp is entropy


There are some animations but
not many physical models
available


While animated models are
helpful to some students, others
need a more hands on approach



Previously Done Demonstrations


Physical Model Examples:


Absolute

Gage Pressure


Vacuum Boiling (Saturation point)

Labs to Reinforce Lessons


Labs that complement in class curriculum are
beneficial for many students
