Abstract
In Part B a computer code, '"MITEMP: M.I.T. Transient Temperature
Prediction Model for Natural Reservoirs and Cooling Impoundments," is
presented as a feasible and efficient tool for the prediction of transient
performance of man-made impoundments. Particular emphasis is placed on
waste heat dissipation from steam-electric power stations. The code
allows the simulation of the physical regime (temperature and flow patterns)
of impoundments as a function of design and for long time periods. The
code contains the following elements: (1) Natural Deep Lake and Reservoir
Model, (2) Deep Stratified Cooling Pond Model, (3) Shallow Vertically
Mixed Dispersive Cooling Pond Model, and (4) Shallow, Vertically Mixed
Recirculating Cooling Pond Model.
The physical and mathematical basis for the present computer code is
developed in an earlier report entitled, "Mathematical Predictive Models
for Cooling Ponds and Lakes, Part A: Model Development and Design
Considerations," by G. Jirka, M. Watanabe, K.H. Octavio, C. Cerco and
D.R.F. Harleman, R.M. Parsons Laboratory for Water Resources and Hydrodynamics,
Technical Report No. 238, December 1978.
The user's manual presented herein gives a detailed description of
the computational structure of MITEMP and discusses input and output
requirements. The application to several case studies is presented. A
complete code listing is given in the appendix, as are some sample
computations.
In Part C, an analytical model is developed to predict the transient
performance of shallow, vertically mixed cooling ponds. This model is
suggested as an aid in the initial design or screening process, eliminating
the need for repeated use of MITEMP for long term simulations. When a
candidate design(s) is selected, its long term performance can be analyzed
with the more precise MITEMP.
